Answer 2

To simplify the expression (-a^7 + b^5)(a^7 + b^5), you can use the difference of squares formula:

a^2 - b^2 = (a + b)(a - b)

In your expression, you have a^7 and b^5, so you can treat it as a^14 - b^10, and then apply the difference of squares formula:

(-a^7 + b^5)(a^7 + b^5) = -(a^7)^2 + (b^5)^2 = -(a^14) + (b^10)

So, the simplified expression is:

-(a^14) + b^10
