Question

can someone solve and show steps for (x+iy)^2=18i

Answer 1

multiply (x+iy)(x+iy)
write what you got when you do that

Answer 2

solve the radical equations and remember to weed out extraneous solutions. \[\sqrt{2x^2+2}=3-x\]

Answer 3

square both sides
2x^2+2=(3-x)^2
2x^2+2=9-6x+x^2
now solve for x
and check both solutions
