Question

What do you get when you subtract (x2– y2) from (y2 – x2).​

Answer 1

Answer:

(x^2 - y^2) from (y^2 - x^2)

=> (y^2 - x^2) - (x^2 - y^2)

=> y^2 - x^2 - x^2 + y^2

=> 2y^2 - 2x^2

Ans. 2y^2 - 2x^2

Hope it helps.

Answer 2

Answer:

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