Question

For what value of x is the equation below true?

x2+4x +5=0

Answer 1

The answer is -2+/- square root of -1.

Answer 2

Hi there!

`\large\boxed{\text{None.}}`

Using the discriminant formula, we can determine if this equation is ever true:

b² - 4ac

Plug in the a, b, and c values from the equation:

(4)² - 4(1)(5)

16 - 20 = -4 < 0

Since the discriminant is less than 0, there are no zeros to the equation. Thus, the equation is never true.
