(x-y) whole square = 4- 4y+y square, so find the value of x??

1.	(x-y) whole square = 4- 4y+y square, so find the value of x??
Answer» ${(x - y)}^{2} = 4 - 4y + {y}^{2} \\ {x}^{2} - 2xy + {y}^{2} = {2}^{2} - 2 \times 2 \times y + {y}^{2} \\ x = 2$

Answer»

${(x - y)}^{2} = 4 - 4y + {y}^{2} \\ {x}^{2} - 2xy + {y}^{2} = {2}^{2} - 2 \times 2 \times y + {y}^{2} \\ x = 2$
