In this example, we're going to be evaluating this expression using what's known as the distributive property.
00:06
And an easy key here is to remember the acronym foil.
00:12
If you haven't heard of this, we have, we're going to first multiply our first terms.
00:18
That's what our f stands for us.
00:20
So let's start there.
00:21
So we're going to multiply our first terms in our parentheses.
00:23
So that's x times 2x.
00:26
And that's going to give us 2x squared.
00:30
Now the o stands for outside, meaning we're going to multiply our outside terms next of this function.
00:36
So we have x times a negative 7, which gives us a negative 7x.
00:44
Next, the i stands for the inside terms that we're going to be using.
00:49
So doing the same thing, we're going to take 9 times 2x...
