Question

Factorize the following expression

(a) x(1-b) -y(1 -b)

(b) 9r(z + 1) + 3r(z+ 1)

(c) p² + q² + 5a(p² + q²)

(d) x² + xy + 8x + 8y

(e) 3(x+y) - 9(x + y)²

(f) 1(3m - 7n) - n(3m - 7n)

(g) (2m - 5) (3a - 2b) - (2m - 5) (2b -

(h) x(1 + y) + (7 + 7y)

Answer 1

Answer:

(a) (1-b)(x-y)

(b) (z+1)(9r+3z)

(c) (p²+q²)(1+5a)

(d) x(x+y)+8(x+y)

= (x+y)(x+8)

(e) 3(x+y)-[3(x+y)]²

= 3(x+y)(1-3(x+y))

= 3(x+y)(1-3x-3y)

(f) (3m-7n)(1-n)

(g)ques incomplete

(h) x(1+y)+7(1+y)

= (1+y)(x+7)
