Question

My last question please help

Answer 1

`2(x + 2)^(2) + (-15x - 3)`

The guy above is correct

Proof :

`2(x + 2)^(2) - 15x - 3 \\ 2((x + 2)(x + 2) - 15x - 3 \\ 2( {x}^(2) + 4x + 4) - 15x - 3`

`2 {x}^(2) + 8x - 15x + 8 - 3 \\ 2 {x}^(2) - 7x + 5`

My workings are in the picture

My asnwer was 5/2 and -1

Answer 2

Explanation:

(2) (x+2)^2 + (-15x -3)

I hope this will be helpful for you.
