factoring out

forgot the x

x^3-3x^2-4x over
x^2-4x

x(x^2-3x-4) over
x(x-4)

x(x+1)(x-4)
x(x-4)

Wowee bethany! You're rapidly approaching Marilyn Vos Savant

ha ha very funny. Who knows between the two of you I may actually get to like Math and come back as a tutor. Don't worry I would stay in the beginning algebra site.

Can you ever forgive me, Bethany? I was wrong about you, sorry.

...looks like jolly had a talk with his sister...

I don't have time to hold grudges. Like I said Math is not my specialty I am well aware of that, but it is clear to see that it is yours. You are one of the lucky ones. My talents lay elsewhere and that is okay. It takes all kinds to make things happen.
I only ask that you remember it is very hard for some to reach out and ask for help. All of my life I have been having people say to me "Don't you get it? It is right there a+b=z blah blah blah." When this happens the person that doesn't get it will often say they do so they do not look stupid. As you can see I got over that phobia long ago, if I don't get it I am not afraid to say hold up. But, there are many school age people out there, my son included that are just starting to go through this now. Be patient. Think of it like cooking. You may say add two eggs to some and they get it, others you may have to say go to the fridge, take out two eggs, crack them etc....

Brilliantly stated, bethany.

It's sure a funny world:
just about nobody cares if they can't run the 100yards dash under 10 seconds;
just about everybody gets bent out of shape if their intelligence is not as "fast" as others.

I.Q. should not stand for Intelligence Quotient; should be Imagination Quotient
