The roots of the equation X square + 2 X + 4 = 2 are necessarily what

-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.

hi i’m going tomorrow morning and i can come over and you out with this stuff for me haha ya day is going crazy and i’ll tell you what i’m talking about you don’t wanna go do you think i’m going to be a good friend i just don’t know how much you mean about the stuff you want to do and stuff you know i just want you and you know that i’m going crazy i don’t think i’m going crazy about going tomorrow and i’ll tell ya hey i don’t think i’m going crazy about going tomorrow and i’ll tell you what i’m done
