Which of the following is a solution of x2 + 4x + 6? −2 + i times the square root of 2 2 + i times the square root of 2 −2 + three i times the square root of 2 −2 + three i times the square root of 2

Option A is correct.

Solution =

Step-by-step explanation:

A quadratic equation is of the form  .....[1]

then, the solution is given by;

 where a, b and c are the coefficients and x is the variable.

Given the equation:

On comparing the given equation with equation [1] we have;

a = 1 , b = 4 and c =6

then;

the solution for the given equation is;

or

We know that : where i is the imaginary part.

or

Simplify:

Therefore, the solution for the given equation is,

-14 is the answer

hope this : ))
