Question

De la suma de x4-6x2y2+y4 con 8xy2+31y4 restar x4+2x2y2+32y4

Answer 1

$x^{4}-6x^{2}y^{2}+y^{4} + (8xy^{2}+31y^{4})$

$x^{4}-6x^{2}y^{2}+y^{4} + 8xy^{2}+31y^{4}$

$x^{4}-6x^{2}y^{2} + 8xy^{2}+32y^{4}$

$x^{4}-6x^{2}y^{2} + 8xy^{2}+32y^{4}-(x^{4}+2x^{2}y^{2}+32y^{4})$

$x^{4}-6x^{2}y^{2} + 8xy^{2}+32y^{4}-x^{4}-2x^{2}y^{2}-32y^{4})$

$-8x^{2}y^{2} + 8xy^{2}-x^{4}$

$-x^{4}-8x^{2}y^{2} + 8xy^{2}$
