Which of the following is a solution of x2 + 2x + 4? −2 + two i times the square root of 3 2 + two i times the square root of 3 1 − i times the square root of 3 −1 + i times the square root of 3

−1 + i times the square root of 3

is the answer.

Step-by-step explanation:

Given is a quadratic equation in x

using completion of squares method

Equate to 0

Take square root

Subtract one from both sides

x = [/tex]-1±i\sqrt{3}[/tex]

The last option namely

−1 + i times the square root of 3 only matches with our answre

Hence last option is right.

step-by-step explanation:

1

yes   because as the functions are graphed they eventually will intersect unless otherwise
