You can put this solution on YOUR website! Express using a positive exponent:
.
Negative exponents signify fractions. So we can re-write this term as . This would give you the positive exponent you're looking for.

Solve solution set:
(x+5)(x-11)(x+4)>0
.
We know that any number multiplied by zero equals zero, right?
So, since the inequality tells us the left side must be greater than zero, none of the three terms can equal to zero.
Can you see why? Because if any of them do, we would end up with 0>0... which would be wrong.
So now we look for valid values in each term.
. must be greater than zero, so x must be any number greater or equal to 6
. must also be greater than zero, so x must be any number greater or equal to 12
. must aslo be greater than zero, so x must be any number greater or equal to 5
.
Solution set: x>=6, >=12, >=5
