Answer 2

Ques 5. A)

Simplifying y²−10y+25.

y²-10y+25

=y²−5y−5y+25

=y(y−5)−5(y−5)

=(y−5)(y−5)

OR (y-5)²

B)

Simplifying a²+12a+36

=a²+6a+6a+36

= a(a+6)+6(a+6)

= (a+6)(a+6)

OR (a+6)²

C)

Simplifying X²-49

X²- (7)²

it is of the form (a²-b²)= [(a+b)(a-b)]

(X+7)(X-7)

D)

Simplifying p²-8p+16

=p²-2(4)(p)+(4)²

=(p-4)² [using a²+b²-2ab]

= (p-4)(p-4)

E)

Simplifying z²-81

z²- (9)²

it is of the form (a²-b²)= [(a+b)(a-b)]

(z+9)(z-9)

F)

Simplifying x²−4x+4

=x²−2x−2x+4

=x(x−2)−2(x−2)

=(x−2)(x−2)

G)

Simplifying x²+10x+24

=x²+6x+4x+24

= x(x+6)+4(x+6)

= (x+4)(x+6)

H)

Simplifying m²-9m+20

= m²-4m-5m+20

= m(m-4)-5(m-4)

= (m-5)(m-4)
