Answer:
x = 5, -2
Step-by-step explanation:
basic format is ax^2 + bx + c. multiply ac and ask urself what # + what is equal to b? those two same numbers should also multiply to get you ac.
x^2 - 3x - 10 = 0
(x-5) (x+2) = 0
x - 5 = 0 and x + 2 = 0
x = 5 and x = -2
So in this case a= 1 and c = -10. -10 x 1 = -10. -5 x 2 is equal to -10 and -5 + 2 gets you -3, which is b.
I don't think I explained it very well but I hope that helps a little :)
13x is that what you meant???

Answer:
3(2x-3)
Step-by-step explanation:
6x-9 Common factor is 3
6x/3 = 2x
-9/3 = -3
3(2x - 3)
