Algebra.Com's Answer #754703 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! Area(A) of a rectangle is length * width \n" ); document.write( ": \n" ); document.write( "We are given the length and area, let w be the width \n" ); document.write( ": \n" ); document.write( "(3x-4) * w = 6x^4 -8x^3 +9x^2 -9x -4 \n" ); document.write( ": \n" ); document.write( "w = (6x^4 -8x^3 +9x^2 -9x -4)/(3x-4) = 2x^3 +3x +1 \n" ); document.write( ": \n" ); document.write( "This problem is solved by polynomial long division \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( " |
