Question

solve (a^2+b^2)-(a^2-b^2) ​

Answer 1

$( { {a}^{2} + {b}^{2} )}^{2} - ( { {a}^{2} - {b}^{2} )}^{2} \\ ( {a}^{4} + {b}^{4} + 2 {a}^{2} {b}^{2} ) - ({a}^{4} + {b}^{4} - 2 {a}^{2} {b}^{2}) \\ {a}^{4} + {b}^{4} + 2 {a}^{2} {b}^{2} - {a}^{4} - {b}^{4} + 2 {a}^{2} {b}^{2} \\ 2 {a}^{2} {b}^{2} + 2 {a}^{2} {b}^{2} \\ 4 {a}^{2} {b}^{2}.$

hopefully its helped u dear :)
