Algebra.Com's Answer #152598 by PRMath(133)\"\" \"About 
You can put this solution on YOUR website!
I think this is your problem:\r
\n" ); document.write( "\n" ); document.write( "\"5b%5E2%284b%5E2-3b%29\"/\"40b%5E3-30b%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There's probably a way to make that fraction look better but I've tried a few times and I haven't mastered it. Clearly, I need a tutor for how to make math problems look good on this website. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Anyway, if the above is your problem, here is what you do.....\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let's first focus on your denominator:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"40b%5E3-30b%5E2\" Is there a number or variable (or both) that is common to both? How about 10b? Do you see how 10b is in \"40b%5E3\" as well as \"30b%5E2\"?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "SO let's factor out that 10b......\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"40b%5E3-30b%5E2\" = \"10b%284b%5E2+-+3b%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So now your new problem (with the revised denominator is)....\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"5b%5E2%284b%5E2-3b%29\"/\"10b%284b%5E2+-+3b%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now can you see that the \"4b%5E2-3b%29\" in the numerator will factor out the \"4b%5E2-3b%29\" in the denominator??\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "SO, now you have:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"5b%5E2%2F10b\" and this can be reduced to\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"1b%5E2%2F2b\" and (you are STILL not done!) this can be reduced to\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"1b%2F2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I hope this helps you. :-)
\n" ); document.write( "
\n" );
