Add the following polynomial of x3+3xy-2×y2+y3,2×3-5x2y-3xy2-2y3<br>​
ANTONII [103]

The addition of the polynomial x^{3}+3xy-2xy^{2} +y^{3} with 2x^{3}-5x^{2} y-3xy^{2}-2y^{3} is  3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}.

What is a polynomial?

⇒ A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

⇒ In the addition of polynomials, the like terms are added while in subtraction, the like terms are subtracted.

Calculation;

We have been given two polynomial which we have to add   x^{3}+3xy-2xy^{2} +y^{3} and 2x^{3}-5x^{2} y-3xy^{2}-2y^{3}

The sign after addition or subtraction will always be of the variable having more value.

(x^{3}+3xy-2xy^{2} +y^{3} )+(2x^{3}-5x^{2} y-3xy^{2}-2y^{3})

On adding like terms with each other

⇒ (x^{3} +2x^{3})+ 3xy-5x^{2} y-(2xy^{2}+3xy^{2})+(y^{3}-2x^{3})

⇒ 3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}

Hence the addition of the polynomialx^{3}+3xy-2xy^{2} +y^{3} and 2x^{3}-5x^{2} y-3xy^{2}-2y^{3} is 3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}.
