Trying to factor by splitting the middle term

2.1 Factoring 9x2-13x-3

The first term is, 9x2 its coefficient is 9 .

The middle term is, -13x its coefficient is -13 .

The last term, "the constant", is -3

Step-1 : Multiply the coefficient of the first term by the constant 9 • -3 = -27

Step-2 : Find two factors of -27 whose sum equals the coefficient of the middle term, which is -13 .

-27 + 1 = -26

-9 + 3 = -6

-3 + 9 = 6

-1 + 27 = 26
