##### 2 Answers

compare this equation with a

a= 3, b=-10, c=-5

Discriminant=

=

= 100+60

=160 which is more than 0

So it has two solutions.

Two

#### Explanation:

For a quadratic in the general form:

the discriminant

indicates the number of solutions:

In this case

so

Further, the discriminant is part of the quadratic formula that gives the actual solutions:

In this case
