what is the value of the discriminant and of the real solutions of the quadratic equation?

Question

5x^2-9x plus 2 equals 0

Answer 1

why not just use conventional math notation?

5x^2-9x+2 = 0

the discriminant is b^2-4ac = 81-40 = 41

Now just use that in the quadratic formula. Since the discriminant is positive, there are two real solutions:

x = (9±√41)/10
