The quadratic formula. Google Classroom. About Transcript. The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√ (b²-4ac))/ (2a) .
In elementary algebra, the quadratic formula (in some countries referenced as Bhaskara's formula) is a closed-form expression describing the solutions of a quadratic equation.
The quadratic formula helps you solve quadratic equations, and is probably one of the top five formulas in math. We’re not big fans of you memorizing formulas, but this one is useful (and we think you should learn how to derive it as well as use it, but that’s for the second video!).
Learn how to solve any quadratic equation using the Quadratic Formula! Discover the sure-fire way of solving equations of the form ax^2+bx+c=0 where "a" does not equal to zero.
The Quadratic Formula uses the " a ", " b ", and " c " from " ax2 + bx + c ", where " a ", " b ", and " c " are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.
The Standard Form of a Quadratic Equation looks like this: a, b and c are known values. a can't be 0. x is the variable or unknown (we don't know it yet) Here are some examples: 2x2 + 5x + 3 = 0. In this one a=2, b=5 and c=3. x2 − 3x = 0.
The quadratic formula allows us to solve any quadratic equation that's in the form ax^2 + bx + c = 0. This article reviews how to apply the formula.
