Sure. So we have -9x, and then we can distribute the negative, just as we would do with a number. That gives us -9x-17-7x. We can combine the -9x and -7x to get -16x. Therefore, our answer is -16x-17. Hope this helped!
20x^4-39x^3-16x
Make sure to multiply all the terms by each other in the two parentheses
<span> x^2+8x+12 = </span>(x + 6)(x + 2)
