Factor completely

32x^4-50

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
