(6x-2y)2 = (6x-2y)(6x-2y)
When you mulitply 2 binomials like this you are doing the distributive property, but you have to distrubute BOTH the 6x and the -2y.
The shortcut you hear everyone talk about is FOIL(First, Outside, Inside, Last), but it really is distribution.
First: multiply the first terms together (6x)(6x) = 36x2
Outside: multiply the "outside pair" together (6x)(-2y) = -12xy That was 6x from first binomial and -2y from the second binomial
Inside: multiply the "inside pair" together (-2y)(6x) = -12xy That was -2y from first binomial and 6x from the second binomial
Last: multiply the last terms together (-2y)(-2y)= 4y2
Add all the answers together: 36x2-12xy-12xy+4y2 Combine the xy terms because they are like terms
This simplifies to 36x2-24xy+4y2
Whenever you square a binomial your answer will be 1st term squared + 2(product of the 2 terms) + last term squared.
