Algebra.Com's Answer #126812 by nerdybill(7384) You can put this solution on YOUR website! Apply the special case of sum/difference of cubes: \n" ); document.write( "X^3+ Y^3 = (x + y)(X^2 - XY + Y^2 ) \n" ); document.write( "X^3 -^Y3 = (X - Y)(X^2 + XY + Y^2 ) \n" ); document.write( ". \n" ); document.write( "In your case, it's the second one: \n" ); document.write( "So \n" ); document.write( "x^3-8/x+2 \n" ); document.write( "after factoring the numerator becomes: \n" ); document.write( "(x+2)(x^2 -2x + 4)/(x+2) \n" ); document.write( "canceling like-terms we get: \n" ); document.write( "x^2 -2x + 4 \n" ); document.write( " \n" ); document.write( " |
