Question

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

Answer 1

Answer:

$4x + 13$

Step-by-step 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.

$8 \times 2 - 3 = 13$

so put it all together

$4x + 16 - 13 = 4x + 13$
