Try to factor the equation after bringing all variables to one side and have the entire equation set to zero. After it is factored, you can set the individual factors equal to zero and solve.
A quadratic equation looks like this once all variables are brought to one side:
ax^2+bx+c=0
If the equation is unfactorable, remember the quadratic formula:
(negative b) plus or minus the square root of (b squared minus four ac) all over (meaning divide) 2a.
The parenthesis denote individual factors.

Steps:
1-Try to factor. If factoring does not (and it doesn't work all the time) then
2-use the quadratic formula
The quadratic formula works for all quadratic equations.

You need to know the equation and also keep your numbers in order from highest exponent to the smallest! Make sure you check over your work and don't forget that there are two answers so make sure you use plus or minus (plus sign over subtract sign) or if you are asked solve for both.

1st try factoring. If this doesn't work, use the quadratic formula.

No but it is very easy (well considering what you will learn in college if you take any calculus classes). I don't think it's really hard just time consuming and you have to be careful with the + - signs.
