Question

factorise the following expressions 4x(x-2y)²-12y(x-2y)²​

Answer 1

Factorize:-

4x³ + 64xy² -28x²y - 48xy³

Step-by-step explanation:

4x³ + 64xy² -28x²y - 48xy³

=4x (x – 2y)²– 12 y (x – 2y)²

=4x(x² + 4y² -4xy) -12y (x² + 4y² -4xy)

= 4x³ + 16xy² -16x²y  -12x²y - 48xy³ + 48xy²

= 4x³ + 64xy² -28x²y - 48xy³
