Simplify - 3 (4x^2-6x) + 5x^2+17-2x

The answer is: - 7x^2+16x+17

Use the distributive property and multiply - 3 by 4x and - 6x

Which would look like after (-12x^2+18x)

Then it would look like this: (-12x^2+18x) + 5x^2 + 17-2x

Combine Like Terms

Then add - 12x^2 + 5x^2 = - 7x^2

Then subtract 18x - 2 which equals 16x

Lastly you would leave the 17 alone since this one has no like terms. The answer would be: - 7x^2+16x+17
