Question

The roots of quadratic equation

5x^2-4x+5=05x2−4x+5=0

are :

Real & Equal

Real & Unequal

Not real

Non-real and equal
​

Answer 1

Step-by-step explanation:

It depends on the determinant or discriminant.

D=√b2–4ac

= √16–100

=√–84

Hence, there are no real roots,so the roots are non - real.

By applying the formula (–b +_√b2–4ac)/2a.

We get the roots as –0.4+_√(21)/5i.

So, your answer would be (c) non real.
