d. 3i

anonymous · Answer

That is wrong it should be : C.  -5 + 8i

anonymous · Answer

Tdabboud, -1+6i = 5i, -4+2i = -2i, 5i + -2i = 3i

unklerhaukus · Answer

(-1+6i)+(-4+2i) = -1 +6i -4+2i = -5 +8i

anonymous · Answer

you cannot simply add the i like that. i is an imaginary number so it can only be added with other i's. Not like you have done chaplaps

How would u rewrite this in vertex form 
y=x^2+10x+16 
a.y=(x+5^2)+41                                      c.y=(x+10^2)+11
b.y=(x+10^2)-9                                       d.y=(x+5^2)-9
