Answer 1

=2x^{2} +12x-5[/tex]

Explanation:

`=4x^(2) +8x-2-2x^(2)+4x -3\\=4x^(2)- 2x^(2) +8x+4x-2-3\\=2x^(2) +12x-5`

Answer 2

Answer: 2x^2+12x-5

Explanation:

since you are subtracting, you can multiply the second equation by -1 and just add instead; so you would use the equation:

(4x^2+8x-2)+(-2x^2+4x-3) instead
