Question

Add the following algebraic expressions (i) x³ -2x² + 3xy² -y³ ,2x³ - 5xy² + 3x²y - 4y³​

Answer 1

Step-by-step explanation:

[x^3 - 2x^2 +3xy^2 - y^3] + [2x^3 -5xy^2 + 3yx^2 - 4y^3]

= x^3 + 2x^3 -2x^2 + 3yx^2 + 3xy^2 -

5xy^2 - y^3 - 4y^3

= 3x^3 - 2x^2 + 3yx^2 - 2xy^2 - 5y^3

or 3x^3 - 5y^3 - 2xy^2 + 3yx^2-2x^2...ans
