Algebra.Com's Answer #312361 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! x^3+y^3+3xy(x+y) this equation ans is you know that . (x+y)^3 but how.???? \n" ); document.write( "---- \n" ); document.write( "You have to learn to recognize the pattern. \n" ); document.write( "(x+y)^3 = 3C3x^3 + 3C2x^2y + 3C1xy^2 + 3C0y^3 \n" ); document.write( "---- \n" ); document.write( "= x^3 + 3x^2y + 3xy^2 + y^3 \n" ); document.write( "=============================== \n" ); document.write( "Your x^3 + y^3 + 3xy(x+y) = x^3 + y^3 + 3x^2y + 3xy^2 \n" ); document.write( "Rearrange in decending powers of \"x\" and you get: x^3 + 3x^2y + 3xy^2 + y^3 \n" ); document.write( "which is (x+y)^3 \n" ); document.write( "========================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H \n" ); document.write( " |
