Which expression represents the factored form of 6x^2 - 13x - 5?

a) (2x + 5) (3x - 1)

b) (2x - 5) (3x + 1)

c) (6x-5) (x + 1)

d) 6x + 1) (x - 5)

To FL and add

multiply first terms and multiply last terms and add and see if we get the middle term

example

(x+2) (2x-3) = 2x^2+x-6x

2*2x+x*-3=4x-3x=x=middle term so

a. (2x+5) (3x-1)

2x*-1+5*3x=-2x+15x=13x, no we want - 13x

b. (2x-5) (3x+1)

2x*1+-5*3x=2x-15x=-13x correct

answer is B
