Question

write the expression in the standard form a + bi.
(8 + 8i) - (9 - 7i)
(8 + 8i) - (9 - 7i) = \square (simplify your answer.)

Explanation:

Step1: Distribute the negative sign

$(8 + 8i) - 9 + 7i$

Step2: Combine real parts

$8 - 9 + 8i + 7i = -1 + 8i + 7i$

Step3: Combine imaginary parts

$-1 + (8 + 7)i = -1 + 15i$

Answer:

$-1 + 15i$
