GIVEN:
remember:
And
SOLVE:
start by multiplying the factors:
simplify by combing like terms. Most terms subtract off, leaving:
This can be factored, but it is not a perfect square, which is really what we need to take the square root.
I'm not exactly sure what form they want the answer in...
so taking the square root:
so my best answer is:
or the more factored form:
I'm not sure how else to solve it. Taking the square root doesn't work out super well, so I left it in the most simple form I could.
