Quadratic Equations. Example 1. The solutions of a quadratic equation are 4 and -1. Use their sum and product to find a quadratic equation with those solutions. Solution . For a quadratic equation, ax 2 + bx + c = 0, the sum of the solutions is The sum of the given solutions is We have So, if a = 1, then b = -3. The product of the solutions is

Scottsbluff county booking activityIt is also called an 'Equation of Degree 2'. The general form is ax 2 + bx + c = 0, where a, b, and c are numbers, 'x' represents the unknown value and a ≠ 0, if a equals zero then its a linear equation. Find the roots by Solving quadratic equations using this online Quadratic Equation calculator.

Quadratic formula. The calculator uses the following formula: x = (-b ± √ D) / 2a, where D = b 2 - 4ac This formula calculates the solution of quadratic equations (ax 2 +bx+c=0) where x is unknown, a is the quadratic coefficient (a ≠ 0), b is the linear coefficient and c represents the equation's constant. The letters a, b and c are known numbers and are the quadratic equation's coefficients.
