Question

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

Answer 1

24

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

Answer 2

Discriminant is 24 and the equation has 2 real roots.

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!!!!
