Answer 2

Step-by-step explanation:

we know that a quadratic equation in the form: ax^2+bx+c=0

then to find roots formula: -b±√b^2-4ac/2a

here, in the above equation: a=1, b= 4, c=5

so, by substituting values in given formula...

-4±√(4)^2-4(1)(5)/2(1)

= -4±√16-20/2

= -4±√-4/2

so, here we got two roots: -4+√-4/2, -4-√-4/2

also the roots are imaginary....

hope it helps you!
