![]() The next example shows the steps for solving an equation in quadratic form. Solving quadratics by factoring Google Classroom Learn how to solve quadratic equations like (x-1) (x+3)0 and how to use factorization to solve other forms of equations. If the substitution gives us an equation of the form ax 2 + bx + c = 0, we say the original equation was of quadratic form. Look for this relationship as you try to find a substitution.Īgain, we will use the standard u to make a substitution that will put the equation in quadratic form. Notice that in the quadratic equation ax 2 + bx + c = 0, the middle term has a variable, x, and its square, x 2, is the variable part of the first term. If we can make it fit the form, we can then use all of our methods to solve quadratic equations. Then, we can often make a thoughtful substitution that will allow us to make it fit the ax 2 + bx + c = 0 form. Similarly, sometimes an equation is not in the ax 2 + bx + c = 0 form but looks much like a quadratic equation. To factor the expression x 4 − 4 x 2 − 5, we noticed the variable part of the middle term is x 2 and its square, x 4, is the variable part of the first term. For example, given the equation 2 ( x 2 + 3) 8 x, expand this by. We used the standard u u for the substitution. The first step in solving a quadratic equation is to expand the equation and, if necessary, resolve any problems with fractions. So we factored by substitution allowing us to make it fit the ax 2 + bx + c form. Sometimes when we factored trinomials, the trinomial did not appear to be in the ax 2 + bx + c form.
