Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C. Part A: Expand the expression –7i(2 – 4i) using the distributive property. Part B: Show all work for Part A. Part C: Explain why the expansion in Part A did not result in the need to combine like terms.arrow_forward
