Task 1.33 D) (2x^24)/(x1) : (2)/(x1) = (2x^24*(x1))/((x1)*2)= (2(x^22) * (x1) (x+1)) / ((x+1) (x1) *2) = (2x^2 2 * x^2  1^2)/(x^2  1^2 * 2) I think what happens here is that the 2x2 turns into 0x^2 which is x^2 and i think some of the letters and numbers get shorten. I think x^2   1 ^2 get shorten and removed from the tasks in both sides. So that we end up with (x^2)/(2) and then we change sides of 2 so that we get x^2 (2) = x^2 2. Did i do this task correctly?

This is how I would do it: $\displaystyle \frac{2x^2  4}{x1} \div \frac{2}{x1}$ $\displaystyle =\frac{2(x^2  2)}{x1} \cdot \frac{x1}{2}$ $\displaystyle =\frac{\cancel{2}(x^2  2)}{\cancel{x1}} \cdot \frac{\cancel{x1}}{\cancel{2}}$ $\displaystyle = x^22$
