Find the real values of x and y for which`(1+i)y^2+(6+i)=(2+i)x `

Answer» `(1+i)y^2+(6+i) = (2+i)x`
`=>y^2+iy^2 + 6+i = 2x+ix`
`=>(y^2+6)+i(y^2+1) = 2x + ix`
Comparing real and imaginary parts,
`:. y^2+6 = 2x->(1)`
`y^2+1 = x`
`=>y^2 = x -1 ->(2)`
Putting value of `y^2` in (1),
`=> x-1+6 = 2x => x = 5`
`:. y^2 = 5-1 = 4`
`=> y = +-2`
`:. x = 5, y = +-2.`
