Answer: 2x^2+12x-5
Step-by-step 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
Answer:
=2x^{2} +12x-5[/tex]
[tex]=4x^{2} +8x-2-2x^{2}+4x -3\\=4x^{2}- 2x^{2} +8x+4x-2-3\\=2x^{2} +12x-5[/tex]
