7x^2-9x+5=0 find the Discriminant

and number of real solutions

Discriminant = - 59

There are no real solutions

Step-by-step explanation:

7x^2-9x+5=0

We apply the discriminant formula

D = b^2 - 4*a*c

Where a, b and c are obtained by expressing the quadratic equation in the form ax^2 + bx+c = 0

D = (-9) ^2 - 4 * (7) * (5) = - 59

Since D <0 The solutions are complex conjugates
