Question

Simplify
2(x-3)^2 -7

Answer 1

First, you want to solve (x-3)^2. Which is just (x-3)(x-3). You multiply the first term in the first parentheses with everything in the other, then the same with the second term. You should get: x^2-6x+9.

Now going back to the original equation, you'd have 2+x^2-6x+9 = x^2-6x+2+9=
x^2-6x+11

Answer 2

Sorry, made a little mistake:
Now going back to the original equation, you'd have 2+x^2-6x+9-7 = x^2-6x+2+9-7= x^2-6x+4
