A. x + 3 with a remainder of -2
B. 2x - 3 with no remainder
C. 2x + 1 with no remainder
D. 2x - 5 with no remainder

when you factor 2x^2+3x-9 what do you get?

Answer 2

you know one of the factors could be (x+3)

Answer 3

Would it be b?

Answer 4

you could expand out (x+3)(2x-3) to find out, try expanding it and I will double check your expansion

Answer 5

how?

Answer 6

distribute x to (2x-3)
then distribute 3(2x-3)
and then combine like terms

Answer 7

if it is the correct solution it will match 2x2 + 3x - 9

Answer 8

2x^2+6x-9

Answer 9

(x+3)(2x-3)
2x^2-9x+6x-9
2x^2-3x-9

Answer 10

does it match?
