Algebra.Com's Answer #335240 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! x^3+9x^2+14x=0\r \n" ); document.write( "\n" ); document.write( "The equation can be factored as \n" ); document.write( "x(x^2 + 9x + 14) = 0 \n" ); document.write( "The expression inside the parentheses can be further factored as \n" ); document.write( "(x+7)(x+2) \n" ); document.write( "Writing the fully-factored equation we can immediately read off the 3 solutions: \n" ); document.write( "x(x+7)(x+2) = 0 \n" ); document.write( "So the solutions are x = 0, x = -7 and x = -2 \n" ); document.write( " |
