How Do You Use The Quadratic Formula To Solve A Quadratic Equation In Algebra?
In algebra, a quadratic equation is a polynomial equation of the second degree. The quadratic formula can be used to solve a quadratic equation, of the general form ax ² + bx + c. When you set a quadratic equation equal to zero you get two solutions for the value of x. The quadratic formula will quickly solve the equation for zero. The quadratic equation is derived by completing the square in order to solve for values of x. Have the formula readily available. It is probably easier to memorize and know it. Establish your coefficients. In Algebra, the coefficients are the respective a, b, and c values in the general form equation, ax ² + bx + c. For example in the quadratic equation x ² + 5x + 6 the coefficients are 1, 5, and 6 respectively. Substitute your coefficients (a, b, and c) into the quadratic formula and simplify. The quadratic equation has two solutions given by the quadratic formula indicated by the “+ or -” in the quadratic formula.
