Being asked to subtract the two given polynomials.
00:03
So the first thing we have 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, so we just have to bring each of these terms down, 5x to the 4 minus 6x to the 3rd plus x squared plus 5.
00:17
However, in front of the second set of parentheses, we have a negative sign.
00:21
That needs to get distributed to each term in the second parenthesis.
00:25
But remember, distributing a negative sign just means you have to change the sign of each term.
00:30
So the positive x to the third becomes negative x to the third.
00:34
The positive 11x squared becomes negative 11x squared.
00:38
Positive 9x becomes negative 9x, and negative 3 will become positive 3.
00:43
Now we just have to combine late terms.
00:46
Well, the first term, 5x to the 4, doesn't have a late term.
00:49
So we'll just bring that down.
00:52
Next, for the x to the 3rd, we have negative 6x to the 3rd minus x to the 3rd...
