Question

Please give the step by step answer of:

2 x^2 y^2 - 4 x^2 y^2 + 8x^4 ​

Answer 1

Step-by-step explanation:

8x^4-2x^2 y^2

simplify

8x^4 -2x^2 y^2 extract common factor 2x^2

2x^2(4x^2- y^2)

using expressions p^2-q^2=(p-q)(p+q)

(2m-y)(2m+y)

8x^4-2x^2 y^2 can be transformed as:

-2x^2(-2x -y)(2x+y)
