Dividing x squared Watch

1. Hello, trying to get my head round some algebra, doing okay but still a few concepts I struggle with. Cant find a simple explanation to this.

Can someone explain why 3x² divided by x = 3x,
or similar?

Thanks,
Dan

The rule here is: When you divide you subtract the powers.
So 3x^2 / x = 3x
because x has a power of 1.
Similarly if you divide 3x^4 by x^2 = 3x^2

WHEN YOU DIVIDE YOU SUBTRACT THE POWER
3. Thanks! How about -6x divided by x = -6?
4. because -6x in words is x times minus 6, so if you divide something by x that is a multiple of x the x's cancel out
