Question

9y^2-y+2=0
how many real solutions does the equation have
No real solutions
one real solutions
two real solution

Answer 1

The discriminant of the quadratic equation is given by b^2 - 4ac, where a = 9, b = -1, and c = 2.

Plugging in the values, we get:
(-1)^2 - 4(9)(2) = 1 - 72 = -71.

Since the discriminant is negative (-71 < 0), the quadratic equation has no real solutions.
