Question

factorise the following to get 25 marks and brainlist rank...
a)
$ab - bc - ac + {c}^{2} + ab - bc$
b) 9pq+15qr
c)
$16 {m}^{3} - 24 {m}^{2} + 44m$
d)
$12 {x}^{3} {y}^{4} - 4 {x}^{5} {y}^{2}$
e) ax-bx+by+cy-cx-ay


answer is a) (a-c) (2b-c) ( b) 3q(3p+5r) (c) 4m(4m^2-6m+11) (d) 4x^3y^2(3y^2-x^2) (e) (x-y) (a-b-c) ​

Answer 1

Answer:

A) ab-bc-ca+c^2+ab-bc

2ab-2bc-ca+c^2

2a(b-c)-2bc+c^2

2a(b-c)-c(2b+c)

(a-c) (2b-c)

B) 9pq+15qr {taking3q Common}

3q(3p+5r)

C) 16m^3-24m^2+44m

4m(4m^2-6m+11){taking4mcommon}
