Question

Use the table to find the products of the polynomial

pls help i’m having so much trouble with this and i don’t understand

(x^2 + x - 2)(4x^2 - 8x)

Answer 1

Explanation:

Hello,

The table is as below

`\begin{array}c &2&1&-2\\4&\boxed{4}&\boxed{4}&\boxed{-8}\\-8&\boxed{-8}&\boxed{-8}&\boxed{16}\\\ 0&\boxed{0}&\boxed{0}&\boxed{0} \end{array}`

It gives

`4x^4+(4-8)x^3-(8+8)x^2+16x=4x^4-4x^3-16x^2+16x`

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
