In the above example, you could also rewrite x 2 + x вЂ“ 12 as x 2 вЂ“ 3 x + 4 x вЂ“ 12 first. On the left, list all possible factors of the c term, 6 on the right you'll find the sums. A chart will help us organize possibilities. In this polynomial, the b part of the middle term is 5 and the c term is 6. LetвЂ™s factor the trinomial x 2 + 5 x + 6. Note that you can also rewrite 7 x as 5 x + 2 x. So you can rewrite 7 x as 2 x + 5 x, and continue factoring as in the example above. Do either of these pairs have a sum of 7? Yes, 2 and 5. Look at factor pairs of 10: 1 and 10, 2 and 5. The resulting factors will be ( x + r) and ( x + s).ДЇor example, to factor x 2 + 7 x +10, you are looking for two numbers whose sum is 7 (the coefficient of the middle term) and whose product is 10 (the last term). Rewrite the trinomial as x 2 + rx + sx + c and then use grouping and the distributive property to factor the polynomial. To factor a trinomial in the form x 2 + bx + c, find two integers, r and s, whose product is c and whose sum is b. Fortunately, there's a rule for that.ДЇactoring Trinomials in the form x 2 + bx + c If you rewrite 7 x as 6 x + x, this method wonвЂ™t work.

How do you know how to rewrite the middle term? Unfortunately, you canвЂ™t rewrite it just any way. Group the pairs and factor out the common factor x from the first pair and 2 from the second pair.

Rewrite the middle term 7 x as 5 x + 2 x.
