In Quadratic Factorization using Splitting of Middle Term which is x term is the sum of two factors and product equal to last term. We know split the middle term 6x in the given quadratic as 2x + 4x, so that are not quadratic but can factorized by splitting the middle term. I'll be using –8 and +4 to split the middle term's coefficient of –4. My factorization is (2x – 8)(2x + 4), which I can check by multiplying this back together.
Answer. Consider, 7x2 – 98x + = 0. First find the product of 7x2 and , we get x2. Now notice that we have a negative sign in the middle term. At first glance, it may seem difficult to factor trinomials, but you can take advantage of some How do you know how to rewrite the middle term? . Sometimes, the appropriate number combinations will just pop out and seem so obvious!.
