Question

9х квадрат+15х-60=0 дискриминант

Answer 1

9х² +15х-60=0
Д=15²-4*9*(-60)=2385

Answer 2

To find the discriminant of the quadratic equation 9x^2 + 15x - 60 = 0, we can use the formula:

Discriminant (D) = b^2 - 4ac

In this equation, a = 9, b = 15, and c = -60. Plugging in these values, we get:

D = (15)^2 - 4(9)(-60) = 225 - (-2160) = 225 + 2160 = 2385

Therefore, the discriminant of the quadratic equation is 2385.
