x^6-y^6 fist look at as a difference of squares: (x^3)2 - (y^3)2 =(x^3 + y^3)(x^3 - y^3) Now you have the sum of cubes and the difference of cubes, I assume you know the formulas for those. So you can keep going (x+y)(x^2-xy+y^2)(x-y)(x^2+xy+y^2) would be your final answer.

what is a square,i know it has four sides and blah blah blah,but i need two more answers like it is a kite (not really)!! It is the table supporting the hypotenuse. There is an example... what can your imagination come up with? It has 4 equal sides. It has 4 90-degree angles. ...

A slide-loving pig slides down a certain 35 degree slide in twice the time it would take to slide down a frictionless 35 degree slide. What is the coefficient of kinetice friction between the pig and the slide? I know that when the coefficent of kinetic fricition is zero t=1/2...

Imagine a landing carft approaching the surface of Callisto, one of Jupiture's moons. If the engine provides an upward force (thrust) of 3260 N, the craft descends at constant speed; if the engine provides only 2200 N the craft accelerates downward at .39 m/s^2. a) What is...
