Answer:
14 - 13i
Step-by-step explanation:
We MUST do the work inside parentheses before anything else.
Step 1: evaluate i^2: (2i-1)(i^2-3i-7) = (2i-1)(-1 -3i -7)
Step 2: combine like terms inside the parentheses: (2i-1)(-8 - 3i)
Step 3: perform the indicated multiplication of binomials:
-16i + 6 + 8 + 3i
Step 4: combine like terms of the above expression: 14 - 13i
