for every value of c =0,find all the complex numbers z which satisfy the equation |z|2-2iz+2c(1+i)=0. Share with your friends Share 0 Priyanka Kedia answered this Let z=x+iy, so the given equation becomes,x2+y2-2ix+2y+2c+2ic=0⇒x2+y2+2y+2c-i2x-2c=0-i0Comparing real and imaginary part, we have,2x-2c=0⇒x=cAnd,x2+y2+2y+2c=0⇒y2+2y+2c+c2=0For real value of y, discriminant will be positive. i.e.,4-42c+c2≥0⇒c2+2c-1≤0⇒c+2+1c-2-1≤0⇒0≤c≤2-1For, c=0, y=0,-2So, z=0 , -2i 12 View Full Answer
