If c (x) = 4x – 2 and d(x) = x2 + 5x, what is (cd) (x)
1 answer:
c(x) = 4x - 2
d(x) = x^2 + 5x
4x - 2(x^2 + 5x)
<em><u>Using FOIL, distribute each term appropriately. </u></em>
4x^3 + 20x^2 - 2x^2 - 10x
<em><u>Combine like terms.</u></em>
4x^3 + 18x^2 - 10x is the simplified polynomials achieved when c(x) and d(x) are multiplied.

9x17 is greater. I’d say you can tell because 17 is greater than 15 so the product would be greater too
