Question

Factorise using identity 9x 2 -24xy+16y 2

Answer 1

9x²-24xy+16y²

(3x)²-2*3x*(-4y)+(4y)²
This is in the form of (a-b)²
a²-2ab+b²= (a-b)²

(3x-4y)(3x-4y)
(3x-4y)²

Answer 2

Answer:

9x²-24xy+16y²

(3x)²-2*3x*(-4y)+(4y)²

This is in the form of (a-b)²

a²-2ab+b²= (a-b)²

(3x-4y)(3x-4y)

(3x-4y)²

(3x-4y) (3x-4y)- This is the irreducable form
