Question

can someone help me with this quadratic equation that has imaginary numbers?

Answer 1

Given:

$x^2-8x+20=0$

We will calculate the discriminant of the given quadratic equation

First, we will identify the coefficients:

a = 1, b = -8, and c = 20

the discriminant will be as follows:

$D=b^2-4ac=(-8)^2-4(1)(20)=64-80=-16<0$

The discriminant is less than zero

So, the roots are imaginary numbers or (complex numbers)
