Step-by-step explanation:
(3 + 2i)(1 + iy)
= 3 + (3y + 2)i - 2y (because i² = -1)
For this to be real, (3y + 2) = 0. => y = -2/3
For this to be imaginary, y can be any real or complex number (except -2/3)
Answer:
5556587 x 10^-2
First you have to multiply negative four in parentheses, then add minus two
-4×(-8+3x)=32-12x
2+32-12x=34-12x
34-12x=82
-12x=48
x=-4
