Question

Simplify the expression (-2+4i)-(2+7i) I am not great at these--

Answer 1

$( - 2 + 4i) - (2 + 7i) \\ ( - 2 + 4i) + ( - 2 - 7i) \\ - 2 + ( - 2) = - 4 \\ 4i + ( - 7i) = - 3i \\ - 4 - 3i$

Answer 2

(-2+4i)-(2+7i)
-2+4i+(-2-7i)
Remove ( )
-2+4i+-2-7i
-4+4i-7i
-4-3i Is the answer. Nope this helps.
