Problem we're being asked to subtract the two given polynomials.
00:03
So the first thing we need to do is get all of the terms out of the parentheses.
00:07
Notice there's nothing in front of the first set of parentheses.
00:10
So all of those terms will come down.
00:12
The 8x to the third plus 5x squared minus 3x plus 1.
00:17
Now in front of the second set of parentheses, we have a negative sign.
00:20
That needs to get applied to each term in the second set of parentheses.
00:24
While distributing that negative just changes the sign of each term.
00:28
So the negative 5x to the third, becomes positive 5x to the 3rd.
00:33
The positive 6x becomes negative 6x, and the negative 11 becomes positive 11...
