    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

    Thanks! How about -6x divided by x = -6?

    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
