Question

(x-4)(x^2-3x+2)

what’s that equal

Answer 1

`x^3 - 7x^2 + 14x - 8`

Explanation:

To multiply two polynomials together, multiply every term of the first polynomial by every term of the second polynomial. Then combine like terms.

`(x-4)(x^2-3x+2) =`

First, multiply x by every term of the trinominal. Then, multiply -4 by every term of the trinomial.

`= x^3 - 3x^2 + 2x - 4x^2 + 12x - 8`

Now combine like terms.

`= x^3 - 7x^2 + 14x - 8`
