Question

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

and number of real solutions

Answer 1

Discriminant = -59

There are no real solutions

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
