Answer 9

Sorry i had to erase my whole paragraph b/c i ended up with two variables and i'm trying to come up with another linear equation to solve the system.

I started with factoring out the 5 then using the quadratic equation to figure out what b is by trying to solve for the discriminant (what's inside the square root in the quadratic equation)... but if i figure it out i'll let you know. i have homework myself i need to finish so if i get around to it i'll post it :-)
