Question

x^4 + x^2 y^2 + y^4. factorise it​

Answer 1

Answer:

${x}^{4} + {x}^{2} {y}^{2} + {y}^{4}$

$({x}^{2} + {y}^{2} ) ^{2} - {x}^{2} {y}^{2}$

$( {x}^{2} + {y}^{2} )^{2} = {x}^{2} {y}^{2}$

${x}^{2} + {y}^{2} = xy$

${x}^{2} - xy + {y}^{2} = 0$

${(x - y)}^{2} + xy = 0$

$x - y = \sqrt{xy}$

Hope it is right and will help you
