Question

If using the method of completing the square to solve the quadratic equation x 2 + 2 x + 16 = 0

Answer 1

Explanation:

`x^(2) +2x+16=0\\x^(2) +2x+1-1+16=0\\(x^(2) +2x+1)-1+16=0\\(x+1)^(2) +15=0\\(x+1)^(2)=-15`

The solution does not exist because all numbers squared are greater than zero.
