We apply the power rule to x to the sixth. We bring the six out front or multiply the one coefficient here times six to get six x to the fifth, decrement that exponent, minus, bring the five times the three, minus 15 x to the, we decrement the five, so x to the fourth. And we need to figure out over what intervals is this going to be less than zero? And now let's see how we can simplify this a little bit. Both of these terms are divisible by x to the fourth and they're both divisible by three. So let's factor out a three x to the fourth times, you factor out a three x to the fourth here, you're left with a two x. And then over here you have minus five has to be less than zero.
