WebYou can use the Quadratic Formula any time you're trying to solve a quadratic equation — as long as that equation is in the form "(a quadratic expression) that is set equal to zero". Often, the simplest way to solve " ax 2 + bx + c = 0 " for the value of x is to factor the quadratic , set each factor equal to zero, and then solve each factor. WebJun 8, 2024 · Method 1 - Factorising the Equation If the quadratic equation has real, rational solutions, the quickest way to solve it is often to factorise into the form (px + q) (mx + n), where m, n, p and q are integers. This is especially true where the coefficient of x 2 is 1. Example 1 - Solve x 2 +7x+12=0
WebSolving quadratic equations by completing the square Consider the equation x^2+6x=-2 x2 +6x = −2. The square root and factoring methods are not applicable here.
