This problem, we're being asked to subtract the two given polynomials.
00:04
So the first thing we need to do is remove both sets of parentheses.
00:07
Now, there's nothing in front of the first set of parentheses, so none of the first three terms change.
00:12
We have negative 7x squared, minus 5x, minus 8.
00:16
Now, because there's a minus sign in front of the second set of parentheses, we need to change the sign of each term in the second set of parentheses.
00:25
So the negative 4x becomes positive 4x, the negative 9x squared becomes positive.
00:30
Of 9x squared, and the positive 10 becomes negative 10.
00:35
Next, we're going to combine our like terms...
