What is the discriminant of the quadratic equation 2x+5x^2=1

D.24

Step-by-step explanation:

Discriminant is 24 and the equation has 2 real roots.

Step-by-step explanation:

To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.

• yields 2 real roots

• yields 1 real root

•[tx]b^2-4ac<0[/tex] yields no real roots

Our the equation is can be arranged to where a=5, b=2, and c=-1.

. The equation has 2 real roots .
