Simplify the expression (4-5i)(2+6i)-(3-2i) show your work.
Anastaziya [24]

The simplification of the given expression (4-5i)(2+6i)-(3-2i), we get -30i^2+16i+5.

Given expression is:

  • (4-5i)(2+6i)-(3-2i)

By applying the multiplication, we get

→ (8-10i+24i-30i^2)-(3-2i)

By multiplying the (-) sign into the bracket, we get

→ 8-10i+24i-30i^2-3+2i

→ 5+16i-30i^2

By arranging the terms, we get

→ -30i^2+16i+5

Thus the answer above is right.
