5 can't be B as the three roots must multiply for positive 42

C.

use distance formula on both and set them equal. you get it out with some mild algebra bashing
I left it to the end but ran out of time and guessed C, yassss

You don't need any serious algebra for Q10.
Assume a>0, b>0, b>a (or the other way round if you like), then draw a diagram.
By symmetry you can see that it must pass through the origin, eliminating B and D.
Then you just need to choose the option with the correct gradient.
