Question

multiply the polynomials (5s + 3)(s^2 + s - 2)

Answer 1

\[5s^3+8s^2-7s-6\]
or, if you want it simplified...
\[(x-1)(x+2)(5x+3)\]

Answer 2

changes the x's to s's I'm too used to working in that var.

Answer 3

(5s+3)(s^(2)+s-2)

Multiply each term in the first polynomial by each term in the second polynomial.
(5s*s^(2)+5s*s+5s*-2+3*s^(2)+3*s+3*-2)

Multiply each term in the first polynomial by each term in the second polynomial.
(5s^(3)+8s^(2)-7s-6)

Remove the parentheses around the expression 5s^(3)+8s^(2)-7s-6.
5s^(3)+8s^(2)-7s-6
