Compute the value of the discriminant and give the number of real solutions to the quadratic equation.

2x^2+5x-7=0

Discrimnant=

number of real solutions=
Answered by Diana
The discriminant is b^2-4ac

I won't do all the work for you, but figure that number out.
-If its positive, theres two solutions
-If its negative there are no solutions
-If its zero theres one solution.
