Squares

Example: Squaring Binomials

We have to square (6+y)^2 for problem 1, right? Well, it would be easier to read as (y+6)^2

Next, you have to use the FOIL method of distributing polynomials, FOIL stands for First Outer Inner Last

(y+6)^2 = (y+6)(y+6), right?

First:  multiply both the y's together = y^2
Outer: Multiply the "y" on the first binomial with the "6" on the 2nd binomial = 6y
Inner: Multiply the "6" on the first binomial with the "y" on the 2nd binomial = 6y
Last: Multiply both the "6"'s together = 36

NOW, add them all together = y^2 + 12y + 36

Now, for SQUARING binomials, there is a formula you can use.
a^2 + 2ab + b^2

Lets look back at the previous binomial
"y" is a
"6" is b

SUBSTITUTE:

y^2 + 2(y)(6) + 6^2 =
y^2 + 12y + 36


there ya go, you now know how to square binomials~!~~~~!!!!!!!!!!!!!!!
