Question

Written as a simplified polynomial in standard form, what is the result when (2x + 8)2 is subtracted from 8x2 – 3?​

Answer 1

`4x + 13`

Explanation:

first solve the first part then subtract it from the other part.

`(2x + 8)2 = 4x + 16`

that is the first part.

the second part solve it too.

`8 * 2 - 3 = 13`

so put it all together

`4x + 16 - 13 = 4x + 13`
