Question

Identify the polynomial that is not the difference of two squares. HELP PLEASE!!!

4x^6 − 9y^6
16x^2 − 625
80x^6 − 9y^4
169x^2 − 4y^4

Answer 1

80x^6 − 9y^4

Explanation:

A polynomial which is a difference of two squares has the form
`a^2-b^2` where a and b are perfect squares.

Of the options 80x^6 − 9y^4 does not follow this form because 80 is not a perfect square.
