Using The AC Method To Factor A Trinomial When a>1
To
factor a trinomial when a>1 such as
2x^{2}+
5 + 11x 

First be sure to put it in
descending order so that the term of highest degree ax^{2} is first
followed by the term bx and c last. In this case we rewrite 2x^{2}+ 5 + 11x as 2x^{2}+ 11x + 5 

Second find the product of a and c in ax^{2}+bx +c. In this case a=2 and c=5. The product ac=2(5)=10


Third in order to factor 2x^{2}+ 11x + 5 we need factors of 10 that sum to the coefficient of the middle term 11. The table below will help us to find the factors. 

The factors we want to use are 1 and 10.Next page
