Answer:
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
Hope this helps!!!!

Answer:
24
Step-by-step explanation:
First off, we must rewrite this quadratic in proper quadratic form:
5x^2 + 2x - 1. Then a = 5, b = 2 and c = -1, and the discriminant, b^2-4ac, is:
2^2 - 4(5)(-1) = 4 + 20 = 24
