If A = 2 s2 - 10s – 10 and B = -s-2, find an expression that equals
2A - 2B in standard form.

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
