Question

Factor completely
32x^4-50

Answer 1

Answer is:


32x^4 -50
=2 (16x^4 -25)
= 2(4x^2+5)(4x^2-5)

This factoring is called a difference of squares because it only has two terms and the exponent is even and the last number is a negative

It can be the other answer since (a+b)^2 will always have three terms when expanded. a^2 + 2ab+b^2

Answer 2

2(4x^2-5)^2

Explanation:

If you divide two, you would get 2(16x^4-25). Then 16 and 25 are perfect squares. So you would get 2(4x^2-5)^2
