To solve quadratic equations start by combining all of the like terms and moving them to one side of the equation Then factor the expression and set each set of parentheses equal to 0 as separate equations Finally solve each equation separately to find the 2 possible values for x 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

The formula for a quadratic equation is used to find the roots of the equation Since quadratics have a degree equal to two therefore there will be two solutions for the equation Suppose ax bx c 0 is the quadratic equation then the formula to find the roots of this equation will be x b b2 4ac 2a The formula to find the roots of the quadratic equation is x b b 2 4ac 2a The sum of the roots of a quadratic equation is b a The product of the Root of the quadratic equation is c a The quadratic equation whose roots are is x 2
The Quadratic Formula is a rule that says that in any equation of the form ax2 bx c 0 the solution x values of the equation are given by x dfrac b pm sqrt b 2 4ac 2a x 2a b b2 4ac Solving quadratics by factoring Google Classroom Learn how to solve quadratic equations like x 1 x 3 0 and how to use factorization to solve other forms of equations What you should be familiar with before taking this lesson Factoring using the Sum Product pattern Factoring by grouping Factoring special products
