Question

(-x^4-xy^3+y^4)+(x^4-x^3y-5xy^3+xy^3)-(7x^4+2x^3y-xy^3) =?

Answer 1

let's get rid of the parentheses \[\large -x^4 - xy^3 + y^4 + x^4 - x^3y - 5xy^3 + xy^3 - 7x^4 - 2x^3y + xy^3\] is that easier??

Answer 2

sory but i still cant get it

Answer 3

how abt if we join like terms \[(-x^4 + x^4 - 7x^4) + (-xy^3 - 5xy^3 + xy^3+xy^3) + (-x^3y - 2x^3y - x^3y) + y^4\]
