Question

Discuss the nature of the roots of the equation 4x^2 -2x – 5= 0

Answer 1

Answer:

0.125 ± 1.11

Step-by-step explanation:

4 x 2 + x + 5 = 0 Comparing with standard quadratic equation a x 2 + b x + c = 0 a = 4 , b = 1 , c = 5 Discriminant D = b 2 − 4 a c or D = 1 − 80 = − 79 If discriminant positive, we get two real solutions, if it is zero we get just one solution, and if it is negative we get complex solutions.
