The reason is that if you did the normal operations it would result like

The reason is that if you did the normal operations it would result like(a + b)^2 = (a +b)(a + b) =

= a^2 + ab + ab + b^2 =

= a^2 + 2ab + b^2

So here you have the same result, that's just a shorter way to do this… the rule is that:

(When you have a binomial squared)

First letter (or number) squared

Second letter (or number) squared

The double of their product

So let's try that with numbers:

(5a + 4b)^2 = 25a^2 + 16b^2 + 40ab

If you don't trust me or this “shortcuts” you can just do all the operations :)
