complex sum on complwn noss>>>>>

soln of equation
mod z - z =1 + 2i
it seeeems easy quadratic type
i replaced z by âˆšx² + y²
z by x + yi . but it seeems lil dufficult .

answer is x = 3/2 y = -2

can witout quad this b solved >>>>>>>??>>>>>>>>

âˆš(x²+y²)-x-iy=1+2i

equating the real and imaginary parts

y=-2

and âˆš(x²+y²)-x=1
put y=-2 in this
âˆš(x²+4)=1+x

squaring we get x²+4=1+x²+2x
x=3/2

ohhhhh it jus had 2 equate an i madly
was doin quadraticly
