What is Quadratic Formula?
The quadratic formula is a mathematical equation that solves for the roots (or solutions) of a quadratic equation. A quadratic equation is an equation of the form:
ax^2 + bx + c = 0
where a, b, and c are constants, and a ≠ 0. The roots of the equation are the values of x that make the equation true.
The quadratic formula is:
x = (-b ± √(b^2 - 4ac)) / 2a
where:
- b is the coefficient of the x term
- c is the constant term
- a is the coefficient of the x^2 term (and must not be equal to 0)
- ± means “plus or minus”
- √ means “square root”
