Quizplus · Accepted Answer

To simplify the expression, add the real parts and the imaginary parts separately: (-8 + 11) + (4i + 4i) = 3 + 8i.

Simplify Write Your Answer in the Form a + Bi (−8+4i)+(11+4i)( - 8 + 4 \mathrm { i } ) + ( 11 + 4 \mathrm { i } )(−8+4i)+(11+4i)

Simplify Write Your Answer in the Form a + Bi $( - 8 + 4 \mathrm { i } ) + ( 11 + 4 \mathrm { i } )$
