First, factorise both the top and the bottom expressions. What is the common factor for the top expression? (expect an answer of x). If you factorise out the x, what are you left with? (expect x(x+3))What...

y = x³- 2xdy/dx = 3x² -2plugging in x = 2, therefore gradient = 10using the formula to get the equation of a line y -y₁=m(x - x₁)substitute y₁=4 and ...

First of all, you are trying to prove that these two lines are parallel. So how would we be able to show this… Well two lines are parallel to one another if they have the same gradient (draw demonstration...

First thing to do is practice. Practice makes perfect. You are not going to get through your differentiation and integration by doing only a couple of questions on these topics. You need to take one topic...
