Answer:
Step-by-step explanation:
(1) 
First, let's expand the expression:


Next, let's factor the quadratic:

Finally, set the equation equal to
to find the solutions


(2) During the step
, when you take the square root of both sides, you have two equations, rather than one:
and
, so the solutions should be 
(3)

Add
to both sides

Multiply both sides by 

Take the square root of both sides
±
Subtract
from both sides
