Question 434196: I am having trouble remembering the basics of functions! here is my question:
if p(x) = (x+3)squared
and q(x) = 3-x
solve such that p(x) = q(x)
I just set the two functions equal to each other and get xsquared + 7x = -6, but what does that mean?

You can put this solution on YOUR website!
if p(x) = (x+3)squared
and q(x) = 3-x
solve such that p(x) = q(x)
--------------
x%2B3%29%5E2+=+3-x
x%5E2+%2B+6x+%2B+9+=+3-x
x%5E2+%2B+7x+%2B+6+=+0
(x+1)*(x+6) = 0
x = -6, -1
-----------
Those are the 2 values of x that make p(x) = q(x)
