Slide Method for Factoring Trinomials in the form So you want an easier way to factor trinomials?
Let’s start with this example: Take the coefficient of the and multiply it by the constant. 6 (-15) = -90 Rewrite the equation with a coefficient of “1” for the term and the -90 as the constant. Factor the trinomial. (x – 10)(x + 9) Now divide each of the numbers by the original coefficient of “6”. And simplify The numbers in the denominator now are moved to be the coefficient of x! (3x – 5)(2x + 3)
Let’s look at another example: Take the coefficient of the and multiply it by the constant. 10 (-7)= -70 Rewrite the equation with a coefficient of “1” for the term and the -70 as the constant. Factor the trinomial. (x – 2)(x + 35) Now divide each of the numbers by the original coefficient of “10”. And simplify The numbers in the denominator now are moved to be the coefficient of x! (5x– 1)(2x + 7)
Your Turn Factor the following trinomial using the “slide method for factoring” + 8x – 35 + 8x – 105
With a partner explain the steps for using the slide method for factoring! How easy was that?
