![]() ![]() In the given quadratic equation, the coefficient of x 2 is not 1. In the given quadratic equation, the coefficient of x 2 is 1.ĭecompose the constant term +14 into two factors such that the product of the two factors is equal to +14 and the addition of two factors is equal to the coefficient of x, that is +9.įactor the given quadratic equation using +2 and +7 and solve for x.ĭecompose the constant term +14 into two factors such that the product of the two factors is equal to +14 and the addition of two factors is equal to the coefficient of x, that is -9.įactor the given quadratic equation using -2 and -7 and solve for x.ĭecompose the constant term -15 into two factors such that the product of the two factors is equal to -15 and the addition of two factors is equal to the coefficient of x, that is +2.įactor the given quadratic equation using +5 and -3 and solve for x.ĭecompose the constant term -15 into two factors such that the product of the two factors is equal to -15 and the addition of two factors is equal to the coefficient of x, that is -2.įactor the given quadratic equation using +3 and -5 and solve for x. ![]() (iv) Write the remaining number along with x (This is explained in the following example). ![]() (iii) Divide the two factors by the coefficient of x 2 and simplify as much as possible. (ii) The product of the two factors must be equal to "ac" and the addition of two factors must be equal to the coefficient of x, that is "b". (i) In a quadratic equation in the form ax 2 + bx + c = 0, if the leading coefficient is not 1, we have to multiply the coefficient of x 2 and the constant term. Solving Quadratic Equations by Factoring when Leading Coefficient is not 1 - Procedure Positive sign for smaller factor and negative sign for larger factor. ![]()
