An expression involving complex numbers is shown. 3(5+ 6i) Which statement explains the first step that should be taken to simplify this expression? Eliminate an i2 term, because i = -1. %3D B Combine 5 and 6i, because operations within parentheses should be performed first. O Use the distributive property, because multiplying 5+ 6i by 3 should be performed before squaring. DExpand (5 + 6i) as (5+ 6i)(5 + 6i), because squaring means to multiply the complex number by itself.
