Question 519089: for the following equation state the value of the discriminate and then describe the nature of the solutions.
9x^2+2x-8=0
what is the value of the discriminate?
which one of the statements below is correct?
A. the equation has two imaginary solutions
B. the equation has one real solution
C. the equation has two real solutions.
I think the answer to the second part is C but I do not know the first part

let's call the discriminate d
d= (-2)^2 - 4*9(-8)
= 4 + 288
= 292
since the discriminate d is a positive number and is different from 0, the equation has two real solution. so the answer is C.
