Question 181594
<font face="Times New Roman" size="+2">

Missed it by <i><b>that</b></i> much.

*[tex \LARGE \text {          }\math 4i(-7 + i) = -28i + 4i^2 = -28i + 4(-1) = -4 - 28i]

You lost a pesky little <i>i</i> in your process, not to mention a bit of confusion over signs -- or perhaps you inserted an <i>i</i> where there wasn't one.  But a valiant try, nonetheless.  Keep it up.
