just practicing for act

[rumblebeechick]

2ysquared-4y-6=?

 

[Gene]

Assuming you are factoring?
2y²-4y-6 =
2(y²-2y-3)
The factors of 3 are 1 and 3.
2(y-?)(y+?)

 

[rumblebeechick]

the answers the practice test gives is -4,-2,-1,2,4

 

[Gene]

Apparently you are not factoring. Are you evaluating when y = some number that you are keeping secret?

[Gene]

That doesn't answer my question. What instructions are you given?

[rumblebeechick]

i am sorry its late but it says What is the sum of the solutions of the equatiion

 

[Gene]

Okay, you are factoring. That brings us back to my first answer. One of the ?s is 3 and the other is 1. Do you know what that makes the solutions?
