How Do You Factor A Second-Level Polynomial Using The Quadratic Equation?
In algebra, the term “polynomial” refers to an equation with different powers of variables. A second-level polynomial is one where the highest power in the equation is a two: x^2 + 4x -3 = 0, for example. This tutorial shows how to solve for “x” in this equation using the quadratic formula. Set the polynomial equation equal to zero by moving all terms to one side. Set the variables to follow the pattern ax^2 + bx + c, where “a” is the coefficient of the “x-squared” term, “b” is the coefficient of the “x” term, and “c” is the constant. These values will be plugged into the quadratic formula. Use the quadratic formula: (-b±√(b^2-4ac))/2a. Following the pattern ax^2 + bx + c, plug the “a,” “b” and “c” coefficients into the formula. This should result in two answers due to the ± operation. Both answers are legitimate and show what “x” equals.
