-8

Step-by-step explanation:

Note that

   a^2 - b^2

    = a + b

        a -b

which is easier to evaluate when a and b are given.

Here, a + b = -3 + (-5) = -8

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros
