In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation. […]
Given a general quadratic equation of the form
\(ax^2+bx+c=0\)
with x representing an unknown, with a, b and c representing constants, and with a ≠ 0, the quadratic formula is:
\(x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}\)
where the plus–minus symbol “±” indicates that the quadratic equation has two solutions.[1] Written separately, they become:
\(\displaystyle x_{1}={\frac {-b+{\sqrt {b^{2}-4ac}}}{2a}}\quad {\text{or}}\quad x_{2}={\frac {-b-{\sqrt {b^{2}-4ac}}}{2a}}\)
