Arrange the complex numbers in order according to the quadrant in which they appear, starting with the first quadrant. 1. 3 − 4i 2. -1 − 3i 3. 4 + i 4. -2 + 2i
A+bi is the form of a complex number. a is on the x axis, bi is on the y axis: 3-4i ( x positive, y negative) Q4 -1-3i (both x, y negative) Q3 4+i ( both x, y positive) Q1 -2+2i (x neg, y pos) Q3
