How do you simplify (12xy)^2
2 answers:
I believe your answer is 144x^2 y^2
First you need to square the equation so
(12xy) * (12xy)
Then you use the distributive property and simplify
144 + 12x + 12y + 12x + x^2 + xy + 12y + xy + y^2
Then you combine like terms
144 + 24x + 24y + x^2 + 2xy + y^2
Then you sort your equation
x^2 + y^2 + 2xy + 24x + 24y + 144
