Complex Numbers forms

For, z=(4-x, 2x-4)

a) Write z in the rectangular form

Write your answer in the format (a)+(b)i

With a and b values inside the parentheses,  no spaces; e.g. (5x+2)+(6x-2)i

For, z=(4-x, 2x-4)

b) Determine x for real part > 0

For, z=(4-x, 2x-4)

c) Determine x for z to be a real number
