Quadratic Formula
Quadratic Formula: x=(-b +- sqrt(b^2-4ac))/2a
If you have a binomial f(x) = ax^2+bx+c = 0 where a, b, and c are constants then plug them into the Quadratic Formula to find the roots of equation.
For example: f(x)=4x^2+5x+1 then let a=4, b=5, and c=1. We plug these into the quadratic formula and get
x=(-5 +- sqrt(5^2-4(4)(1)))/2(4)
x=(-5 +- sqrt(9))/8
x=(-5+3)/8, (-5-3)/8
x=(-1/4), -1
