A n s w e r :
To Factorise : m2 + 3m − 4
By splitting the middle term
= m2 − 4m − m − 4
= m (m + 4) −1(m + 4)
= (m−1) (m+4)
So, m2 + 3m − 4 = (m−1) (m+4)

The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities.
The formula for direct variation is
y=kx (or y=kx )
where kk is the constant of variation .
The constant of variation in an indirect variation is the constant (unchanged) product between two variable quantities.
The formula for indirect variation is
xy=kx (or y=k/x )
where kk is the constant of variation .

To Factorise : x2+2x−15
By splitting the middle term
=x2+5x−3x−15
=x(x+5)−3(x+5)
=(x−3)(x+5)
So, x2+2x−15=(x−3)(x+5)

p2+5p+6
By splitting the middle term →
= p2+3p+2p+6
=p(p+3)+2(p+3)
=(p+2)(p+3)
So, p2+5p+6=(p+2)(p+3)

(a + b)3 = (a + b)(a + b)(a + b)
Multiply (a + b) and (a + b).
(a + b)3 = (a2 + ab + ab + b2)(a + b)
Simplify.
(a + b)3 = (a2 + 2ab + b2)(a + b)
(a + b)3 = a3 + a2b + 2a2b + 2ab2 + ab2 + b3
Combine the like terms.
(a + b)3 = a3 + 3a2b + 3ab2 + b3
or
(a + b)3 = a3 + b3 + 3ab(a + b)

p4 – (p + q)4
= (p2)2 – [(p + q)2]2
=[p2 - (p+q)2][p2 + (p+q)2]
= {[p -(p+q)][p +(p+q)]}[p2 + p2 + q2 + 2pq]
= {[p -p- q)][p +p+q]}[2p2 + q2 + 2pq]
= { - q)[2p+q]}[2p2 + q2 + 2pq]

10 a² - 20 ab² + 10 b⁴
= 10 a² - 10ab² - 10ab² + 10b⁴
= 10a( a - b²) - 10b² ( a - b²)
= (10a - 10 b²) ( a - b²)

m4 -18m²n²+81n4
=(m2)2-18m²n²+(9n2)2
( a- b)2 = a2 - 2ab + b2
So, (m2)2-18m²n²+(9n2)2 = (m2 - 9n2)2

Construct a quadrilateral ABCD in which AB= 4.2cm, BC= 6cm, CD=5.2cm, DA=5cm and AC= 8 cm.
The given Quadrilateral ABCD can be drawn by following the steps.
Step1: Draw a line AB= 4.2cm
Step2: With A as the centre and radius = 8cm draw an arc.
Step3: with B as the centre and radius = 6cm draw another arc cutting previous arc. Label this point as C
Step4: Join BC
Step5: With A as the centre and radius = 5cm draw an arc.
Step6: with C as the centre and radius = 5.2cm draw another arc cutting previous arc. label this point as D
Step7: join CD and AD.
∴ The constructed quadrilateral looks like:
