Question

What will be the nature of roots of quadratic equation 2x2 + 4x + 7 = 0?

Answer 1

Answer:

The roots are imaginary

Step-by-step explanation:

2x2 + 4x + 7 = 0

a=2,b=4 c=7

so discrimination

b2-4ac=4^2-4*2*7

=16-56

=-40

Here the discrimination is negative

so the roots are imaginary
