Answer:
-1±i
Step-by-step explanation:
Im assuming the question is asking what the roots of x^2+2x+4=2 are.
1. x^2+2x+4= 2 - subtract 2 on both sides to set the quadratic equation equal to zero.
2. x^2+2x+2 - now, since this equation cannot be factored the quadratic formula must be used: -b± (standard form: ax^2+bx+c)
3. -2±/2(1)= (-2±
)/2
4. using complex numbers this can be rewritten as -1±i.
