what is the purpose of a quadratic formula In elementary algebra the quadratic formula is a closed form expression describing the solutions of a quadratic equation Other ways of solving quadratic equations such as completing the square yield the same solutions
The Quadratic Formula uses the a b and c from ax 2 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 Quadratic Formula is derived from the process of completing the square and is formally stated as The quadratic formula helps us solve any quadratic equation First we bring the equation to the form ax bx c 0 where a b and c are coefficients Then we plug these coefficients in the formula b b 4ac 2a

In mathematics a quadratic equation from Latin quadratus square is an equation that can be rearranged in standard form as 1 where x represents an unknown value and a b and c represent known numbers where a 0 If a 0 and b 0 then the equation is linear not quadratic 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 What is the quadratic formula
Quadratic Equation in Standard Form ax 2 bx c 0 Quadratic Equations can be factored Quadratic Formula x b b 2 4ac 2a When the Discriminant b 2 4ac is positive there are 2 real solutions zero there is one real solution negative there are 2 complex solutions 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
