x²+7x+10=0
x²+2x+5x+10=0
x(x+2)+5(x+2)=0
(x+2)(x+5) = 0
x+2 = 0 ; x = -2
x+5 = 0 ; x = -5
Relationship between the zeroes and coefficients :-
Sum of zeroes = -2+(-5) = -2-5
= -7/1 = -x coefficient /x² coefficient
Product of zeroes = (-2)(-5)
= 10/1 = constant/x² coefficient

an arranged series of 4n terms
Total term are even Hence
Median will be mean of 4n/2 & 4n/2 + 1 term
Median Would be Mean of 2n & 2n+ 1 Term
Median = (2n term + (2n+1) term) / 2=( 4n+1)/2

- The resistivity of a material is the resistance of a wire of that material of unit length and unit cross-sectional area. The unit for resistivity is the ohm-metre.
- The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size.
- A good conductor has less resistivity, whereas a bad conductor or insulator has high resistivity.

Given, Quadratic Equation is kx(x - 3) + 9 = 0.
⇒ kx² - 3kx + 9 = 0
On comparing with ax² + bx + c = 0, we get a = k, b = -3k, c = 9.
Given that the equation has real equal and real roots.
∴ D = 0
b² - 4ac = 0
⇒ (-3k)² - 4(k)(9) = 0
⇒ 9k² - 36k = 0
⇒ 9k² = 36k
⇒ 9k = 36
⇒ k = 36/9
⇒ k = 4

Homologous series: A series of organic compounds having similar structures and chemical properties and in which the successive compounds differ by -CH2 group is called a homologous series. A homologue of CH3OH will differ by the -CH2 group; therefore, methanol's successive homologue will be ethanol (C2H5OH).

Let the first term of AP = a
common difference = d
We have to show that (m+n)th term is zero or a + (m+n-1)d = 0
mth term = a + (m-1)d
nth term = a + (n-1) d
Given that m{a +(m-1)d} = n{a + (n -1)d}
⇒ am + m²d -md = an + n²d - nd
⇒ am - an + m²d - n²d -md + nd = 0
⇒ a(m-n) + (m²-n²)d - (m-n)d = 0
⇒ a(m-n) + {(m-n)(m+n)}d -(m-n)d = 0
⇒ a(m-n) + {(m-n)(m+n) - (m-n)} d = 0
⇒ a(m-n) + (m-n)(m+n -1) d = 0
⇒ (m-n){a + (m+n-1)d} = 0
⇒ a + (m+n -1)d = 0/(m-n)
⇒ a + (m+n -1)d = 0

The field of a synchronous generator is the winding to which the DC excitation current is applied. The armature is the winding to which the load is connected. In small generators, the field windings are often on the stator, and the armature windings are on the rotor. The core of an armature is made up of lots of thin metal plates called laminations, which are usually about 0.5mm thick. The thickness of laminations depend upon the frequency at which the armature is designed to work. Laminations are stamped out on a press.

The 'dust of snow' means the fine particles or flakes of snow. The sudden shower in the form of the dust of snow changed the poet's mood. The 'dust of snow' means the fine particles or flakes of snow. The sudden shower in the form of the dust of snow changed the poet's mood. This article focuses on the short poem, Dust of snow summary by Robert Frost. It illustrates the extraordinary curative power of nature and trivial things in life. Nature cures everything whether it is awful mood or illness. The author is experiencing one such bad day when a crow’s movement near hemlock dusted snow upon him. The snow instantly makes him happier. His day gets tons better. The supremacy of nature made him realise his problems are petty. The fact that hemlock is poisonously combined with crow being the indicator of doom and fear is utilized in the poem because the carrier of happiness within the lifetime of the narrator is ironical. The poet tries to spotlight that sometimes creatures link with negative aspects of life often bring change and happiness. Being outdoors in nature, with all its unpredictability can benefit anyone, anywhere at any time.

The functional unit of the kidney is the nephron and it is called the functional unit because its the smallest structure in the kidney that can carry out its functions.

The Statue of Liberty is personified as a female figure who bears the torch of enlightment in one hand and the charter of the rights of man in the other.
The shattered remains of the symbols of Absolutist institutions are shown in the foreground of the image.
In the Utopian views of Sorrieu, people of the world are differentiated through their flags and national costume.

Optical density is the process of transmission of light or other electromagnetic radiation by matter. A measure of the transmittance through an optical medium. In spectroscopy, optical density is the measure of absorbance, and is defined as the ratio of the intensity of light falling upon a material and the intensity transmitted. The optical density of a material relates to the sluggish tendency of the atoms of a material to maintain the absorbed energy of an electromagnetic wave in the form of vibrating electrons before reemitting it as a new electromagnetic disturbance.
