Help would be greatly appreciated!
1) Solve : 2/3(x^2 + 3x - 1)^2 = 3/8
2) Solve the equation, by rearranging and completing the sqaure, finding the exact solutions - 6r^2 + 12r - pr^2 = 50
Thank you in advance!!
The general idea for completing the square is this:
You have something of the form
(You can always reduce your problem to this form.)
Recall that
So we need to find a, then add to both sides.
In your case we have
on the left hand side.
So we need to solve
and then add
to both sides.
