Question

factorise: 8 (x-3y)^2+4 (x-3y)​

Answer 1

$\huge\boxed{\fcolorbox{cyan}{grey}{Solution:-}}$.

➡Factorise of :- 8(x-3y)²+4(x-3y)

↪8(x-3y)²+4(x-3y)

= (x-3y)[ 8(x-3y)+4]

= (x-3y)(8x-24y+4)

Answer 2

Answer:

8(x-3y)^2+4(x-3y)

let x-3y=z.........(1)

8z^2+4z

=4z(2z+1)

on putting the value of z...

=4(x-3y)(2x-6y+1)
