Question

Solve 0 = x2 + 8x + 17 by completing the square.

Answer 1

Answer: ±i-4

Explanation:

To solve this equation by completing the square, we first have to adjust the equation.

Let's rewrite it in this form:

x^2+8x+16+1=0

Then we can complete the square.

(x+4)^2+1=0

(x+4)^2 = -1

x+4 = ±i

x = ±i-4
