Answer:
x=1/3, x=-2/3
Step-by-step explanation:
9x^2 +6x -3x -2=0
6x and -3x add up to 3x. You need four terms to factor.
Then you factor=
3x(3x+2)-1(3x+2)=0
(3x-1)(3x+2)=0
Then you can make two equations
3x-1=0 and 3x+2=0 because to multiply to get 0, at least one will be 0.
3x-1=0
3x=1
x=1/3
3x+2=0
3x=-2
x=-2/3
So your answers are x=1/3, x=-2/3

It cannot be proven true, or proven false, since ''soon'' implicates the future, and it is impossible to know the future. You teacher probably wants you to say something like this.<span />
Do distance divided by time to get the speed.
200 / 2.5 = 80.
The speed is 80 miles per hour(mph).
Hope this helps :)
