Weegy: the answer is D. (3x-4)(2x+5)
well, when u solve this kind of problems, u can check the answer by multiplying the FACTORS.
here, (3x-4)(2x+5)=6x2 + 7x - 20
however, while solving it, the steps r as follows:-
1. first u multiply 6 with 20. [ This gives 120
2.now, u try to find two numbers, which are factors of 120, and give the difference of 7.
here, they r 15 n 8.
3. then u do it as,
6x2 + 15x-8x - 20
=3x(2x+5)-4(2x+5)
=(3x-4)92x+5) ] User: Find the difference.
(9x2 + 10x + 4) - (9x2 + 5x - 1)
A.
5x + 5
B.
15x + 3
C.
x2 + 5x + 5
D.
x2 + 15x + 3
