The Attempt at a Solution

 
Physics news on Phys.org
This should probably be in the Precalculus forum...

For a given quadratic equation, you can solve for the variable by completing the square. Do you need more details than that?
 
1) Factor if you can.

2) Complete the square

3) Use the quadratic formula.
 
Remembering the quadratic formula is useful anyway, because it always works. Even if you think that you should be able to solve it using one of the other methods, but you really don't see it, you can always revert to writing down the quadratic formula and just plugging in the numbers.
