Quadratic Equation

If solving for X in any equation where X is being squared, for example 2x²+4x+2, you can use the quadratic formula.

x= (-b)±√(b²-4ac)
(2a)

'a' is the coeffecient of X², so in this case a=2. b is the coeffecient of X, so in this case b=4. C is the 'plain' number at the end of your equation, so in this case c=2.
