Algebra.Com's Answer #64272 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! For polynomials in two or more variables, the degree of a term is the sum of the exponents of the variables in the term; the degree of the polynomial is again the maximum of the degrees of all terms in the polynomial. For example, the polynomial x^2y^2 + 3x^3 + 4y has degree 4, the same degree as the term x^2y^2.\r \n" ); document.write( "\n" ); document.write( "However, a polynomial in variables x and y, is a polynomial in x with coefficients which are polynomials in y, and also a polynomial in y with coefficients which are polynomials in x.\r \n" ); document.write( "\n" ); document.write( "x^2y^2 + 3x^3 + 4y = (3)x^3 + (y^2)x^2 + (4y) = (x^2)y^2 + (4)y + (3x^3) \n" ); document.write( "This polynomial has degree 3 in x and degree 2 in y. \n" ); document.write( "----------------- \n" ); document.write( "Your Problem: \n" ); document.write( "8x^3 + 6x^2y + 4xy^3 - 2y^4 has degree 4 \n" ); document.write( "As a polynomial in y it has degree 4 \n" ); document.write( "As a polynomial in x it has degree 3 \n" ); document.write( "============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
