Algebra.Com's Answer #670119 by Theo(13342)![]() ![]() You can put this solution on YOUR website! it sounds like you're trying to find the factors. \n" ); document.write( "if that's the case, you could do it in the following manner.\r \n" ); document.write( "\n" ); document.write( "start with 3b^3 -5b^2 + 2b = 0 \n" ); document.write( "replace b with x because it makes it easier to relate to the quadratic formula. \n" ); document.write( "the equation becomes 3x^3 - 5x^2 + 2x = 0 \n" ); document.write( "factor out an x to get x * (3x^2 - 5x + 2) = 0 \n" ); document.write( "this equation is true if x = 0 and or if 3x^2 - 5x + 2 = 0. \n" ); document.write( "factor of x = 0 yields the solution of x = 0. \n" ); document.write( "factor of 3x^2 - 5x + 2 = 0 needs to be factored further using the quadratic formula. \n" ); document.write( "when you use that formula, you get x = 1 or x = 2/3. \n" ); document.write( "your possible solutions are x = 0, x = 1, or x = 2/3. \n" ); document.write( "replace x with b to get b = 0 or b = 1 or b = 1/3.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "if you graph the equation, it will look like this. \n" ); document.write( "1/3 is the same as .6667 as shown in the graph.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " ![]() \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
