Question 116118
2 is a common factor for all the terms, so that is factored out first


2(12x^2+5x-2) ___ now it gets interesting


the factors of "a" (12) have to combine (multiply and add) with the factors of "c" (-2) to get "b" (5)


factors can be positive or negative
factors of "a" are 1 & 12; 2 & 6; 3 & 4 ___ either both positive or both negative
factors of "c" are 1 & 2 ___ one is positive, the other is negative


2 times 4 is 8; -1 times 3 is -3; 8 plus -3 is 5


2(4x-1)(3x+2)
