Rewrite the equation as:
(x + 1)(x + 4)(x + 3)(x + 2) = 120
Multiply the first 2 and last 2 expressions:
{tex}(x^2 + 5x + 4)(x^2 + 5x + 6) = 120{/tex} ..... (1)
Let {tex}x^2 + 5x = y{/tex}
(1) becomes,
(y + 4)(y + 6) = 120
y2 + 10x + 24 = 120
y2 + 10x - 96 = 0
y2 + 16x - 6y - 96 = 0
y(y + 16) - 6(y + 16) = 0
(y + 16)(y - 6) = 0
y = -16 or 6
y2+ 5x = 16 or 6
When x2 + 5x = 6
x2 + 5x - 6 = 0
x2 + 6x - x - 6 = 0
x(x + 6) - 1(x + 6) = 0
(x + 6)(x - 1) = 0
x = -6, 1
When x^2 + 5x = -16
x^2 + 5x + 16 = 0
Using quadratic formula:
{tex}x = [-5 +/- sqrt (25 - 64)]/2{/tex}
The solutions are, -6, 1, [-5 - sqrt (25 - 64)]/2 and [-5 + sqrt (25 - 64)]/2
These are all the possible solutions. But the only real solutions are -6 and 1.

The declining share of agriculture in GDP become a serious concern for India because:
- Reduction of import duties on agricultural product.
- Subsidy on fertilizers has decreased, leading to a rise in cost of production.
- Indian farmers are facing challenge from International competitions.
- Government is reducing investment in agricultural sectors, especially the irrigation sector.
- There are many industries that process crops/ foods from agricultural sector. They will be out of business too. So economy goes down

Given : Line segment joining the points (6,4)and(1,-7) is divided by x axis.
To find : The ratio in the line segment and the coordinates of point of division?
Solution :
Let the line segment points A=(6,4) and B=(1,-7)
Let the line segment divide by x-axis with point P=(x,0)
Let the ratio in which line segment divide be m:n=k : 1
Applying section formula,
Substitute the values,
Compare the y-coordinate,
So, The ratio is 4 :7.
Compare the x-coordinate,
Put the value of k,
So, The coordinate of point of division is

Given:- A circle with center O,PA and PB are tangents drawn at ends A and B on chord AB.
To prove:- ∠PAB=∠PBA
Construction:- Join OA and OB
Proof:- In △AOB, we have
OA=OB(Radii of the same circle)
∠OAB=∠OBA.....(1)(Angles opposite to equal sides)
∠OAP=∠OBP=90(∵Radius⊥Tangent)
⇒∠OAB+∠PAB=∠OBA+∠PBA
⇒∠OAB+∠PAB=∠OAB+∠PBA(From (1))
⇒∠PAB=∠PBA
Hence proved.

The availability of ions is very important to conduct electricity. Distilled water is a pure type of water which does not contain any ions in it. Whereas rainwater contains dissolved gasses such as SO2, CO2.
These gases dissolve in water to form some kind of acids like carbonic acids which dissociates to give ions. Thus rainwater is conducting electricity while distilled water is not conducting electricity.
