What are the solutions for the given equation? X^2 + 4x + 16 = 0

Answer: x=-2 (1-√ 3 ı),-2 (1+√ 3 ı)

Step-by-step explanation:

1. Let y=0 to find the x-intercept (s).

0=x^2+4x+16

2. Switch sides.

x^2+4x+16=0

3. Use the Quadratic Formula.

x = ( -4+4√ 3 ı/2) , (-4-4√ 3 ı /2)

4. Simplify solutions.

x=-2 (1-√ 3 ı),-2 (1+√ 3 ı)
