3 Ways to Find the Roots of a Quadratic Equation wikiHow
A quadratic equation is a trinomial (polynomial with the third degree). Find a, b, and c values by comparing the given equation with ax 2 + bx + c = 0. To find the roots of a quadratic equation, one must solve the equation algebraically using the quadratic formula. To solve an equation using the online calculator, simply enter the math problem in the text area provided. You can find the solutions, or roots, of quadratic equations by setting one side equal to zero, factoring the polynomial, and then applying the zero product property. Applying this in the formula we have the roots as follows: It is not possible to find the square root of a negative number, so the equation has no solutions. No complex numbers will be necessary here:. (x + 2) (x − 3) = 0. Ac is 6× (−6) = −36, and b is 5.
The principle of zero products states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. (x + 2) (x − 3) = 0. Once the polynomial is factored, set each factor equal to zero and solve them separately. When a quadratic equation has been factored, the roots of the equation can be read off. Finding roots of quadratic equation by factoring. The roots of the quadratic equations can be found by the shridharacharaya formula. 6x2 − 4x + 9x − 6. Rewrite 5x with −4x and 9x: Applying this in the formula we have the roots as follows: The left side of the equation is a binomial. Now, the obtained equation is x 2 + (b/a) x + c/a = 0.
