    would the problem that is second from the left of the bottom row be: 2x-14 over x^2+10x+24? Because there was the -x before you simplified to the answer?

      Don't know if it's going to help anyone but here I am a year later asking, wouldn't it be 2x + 14? Not minus?

      no, you cannot divide across addition 5/4+4/5 does not equal 1/4 plus 4/1

    I've once got all my answers on a test with the help of a tutor, wrong and got one correct from my guess since all the tutors were saying that my answer is right, but didn't show to multiply choice.

    @Fan-nr9zp 6 років тому +5

    I really wish you spent time explaining the whole x divides into x2 but x2 can't divide into x. And then u said 5 divides into 5x and 5x divides into 5x... I don't get it.

    • @brianmclogan
      @brianmclogan  6 років тому +10

      x^2=x*x so x^2/x = x*x/x where the x's divide to one leaving you with x so x divides into x^2, x times. Or think about it this way. 4 divides into 12, 3 times because 4*3 = 12. So 5 divides into 5x, x times because 5*x=5x.

    why in example 7, 3(x+6)-1(x+4) didn't get simplified into 3x+18 - x+4 and then using the denominator , it got broken down into 2x+14 over (x+6)(x+4)?
