Factor: 2x^2 + 11x + 15 Which of the following is one of the factors? (2x + 5) (x + 4) (x - 3)

OpenStudy (anonymous):

2x^2 + 6x + 5x + 15 => 2x(x +3) + 5(x+3) => (x+3)(2x+5) hence 2x+5

prashant let me solve some questions jk jk lol

OpenStudy (amistre64):

i would have surmised: +15 has no 4 as a factor, and no -3 since the middle term is +; leaving us with 2x+5
