Simplify the expression. (-4+5i)(5+2i) A. -20+17i B. -10+17i C. -20+10i D. -30+17i Nice try guys lmaoo
first, use FOIL to multiply the first set of coefficients, then outer, then inner, then last. Really you can use any order, but this way keeps you from forgetting a set. so \[(-4*5) + (-4*2i) + (5i * 5) + (5i * 2i)\]
then combine like terms
