We're being asked to determine if the given statement is true or false.
00:04
So we have the quantity of x minus y being squared, and they're saying it's equal to x squared plus y squared.
00:09
Well, in order to figure it out, let's actually do the math part of it.
00:11
So what i think is let's take the binomial, the x minus y that's getting squared, and let's actually go ahead and square it.
00:16
Well, remember, to square something means to multiply it by itself, meaning we would have x minus y times x minus y.
00:24
And because we're multiplying two binomials, we can use the foil method.
00:28
So first we multiply the first terms, x times x, that's x squared...
