We have the function g of x equals x squared minus 2x minus 5.
00:04
So what are the x values that will give us g of x equals 3? let's find out by replacing g of x with 3.
00:11
So we have 3 equals x squared minus 2x minus 5.
00:15
To make this easier to solve, let's subtract 3 from both sides.
00:19
That will give us 0 equals x squared minus 2x minus 8, where 5 minus 3 is 8.
00:26
So now we have to factor this in order to determine what our possible x values.
00:30
Values are going to be.
00:32
So with factoring, we know that this is going to be split up into two different terms in parentheses.
00:37
We know that since this is just x squared, not 2x squared or something, we have just x and x...
