Simplify the expression
(3y+1)^2 + (2y-4)^2
I would start by expanding the two sets of parentheses, then combining like terms. Then take a look at the results and see if it can be factored or otherwise simplified. For example, the first one is
9y^2 + 6y +1.
I also note that a 2 can be factored out of the second set.
Post your work if you get stuck and tell us what you don't understand.
0.03-0.01(x+12)+0.07x=0.02(2x-4)
