Answer:
x²-4x+7
-x²-6x-12
Step-by-step explanation:
1.) the first thing we do is expand the exponent (or mulitply (x-2)(x-2) the images below will show you how to do that
We get x²-4x+4 and then just need to add three
x²-4x+7
2.)
We do the same thing (expand the exponent) and get x²+6x+9
which means so far we have
-(x²+6x+9)-3
carry out the negative sign and subtract 3
-x²-6x-12
