A quadratic equation is any type of equation that can be represented as ax2 + bx + c.
Example:
x2 - 20x + 91 = 0.
(a, b, c are known. They are the coefficients.)
The coefficient of x2 is always a here. In this case, 1.
The coefficient of x = b. In this case -20 (remember it's minus not plus).
C is the constant. In this case that is 91.
The quadratic formula is a straightforward (though it may seem complicated at first) formula which can solve any quadratic equation.

What is the difference between quadratic formula and quadratic equation?
There are an infinite number of different quadratic equations. The quadratic formula is a single formula that can be used to find the pair of solutions to every quadratic equation.
What is the quadratic formula for?
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.
Can the answer to a quadratic equation be a decimal?
Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.
