Answer 2

Answer:

Question :

subtract (x^2 - y^2 + 2xy) from (7x^2 + y^2 - xy)

Solution :

$( {7x}^{2} + {y}^{2} - xy) - ( {x}^{2} - {y}^{2} + 2xy)$

${7x}^{2} + {y}^{2} - xy - {x}^{2} + {y}^{2} - 2xy$

${7x}^{2} - {x}^{2} + {y}^{2} + {y}^{2} - xy - 2xy$

${6x}^{2} + {2y}^{2} - 3xy$

$ans. \: \: {6x}^{2} + {2y}^{2} - 3xy$

Hope it helps.
