All right, so today we're going to learn how to do with 3x plus y to the cube power.
00:06
Just got to remember that when anything is squared or cubed or any number exponentially, that just means that it's that number times that number to the exponential.
00:18
So it's going to look something like this.
00:29
Right? because it's 3x plus y times 3x plus y times 3x plus y times 3x plus y.
00:35
And how you know how many 3x plus ys there are is by the exponential.
00:40
So when you go from here, you foil, which is first, outside, inside, last.
00:55
So you want to multiply each number by each number, just matter keep your place.
01:01
So i've got 9x times 3x, which is 9x squared, 3x times y.
01:08
Which is 3x y and y times 3x which is again 3x y and then y times y which is y square combine your like terms 6x y move all the numbers down and that's that part go ahead and raise on this bring this part up like down lower again, our last 3x plus y here.
01:56
So you want to foil again.
02:01
There's a parentheses...
