Using the discriminant, determine the number of real solutions. 2x^2+7x-15=0 - no real solutions -one real solution -two real solutions

Since discriminant is positive, therefore, the given quadratic equation has two real solutions. Correct answer is the last option.

Step-by-step explanation:

We have been given a quadratic equation and we need to figure out the number of real solutions of the equation.

We know that discriminant of a general quadratic equation is given by

For the given quadratic equation , we have . Upon substituting these values in the formula for discriminant, we get:

Since discriminant is a positive number, therefore, the given quadratic equation has two real solutions. Hence, the last option is the correct answer.
