i) x² + y²- 6x - 4y + 4 = 0 x²- 6x + y² - 4y + 4 = 0 group the terms together x²- 6x = (x - 3)² - 9 factorise the x ter...

To find the quotient and remainder of an algebraic division we use a technique similar to long division at GCSE. I think the best and easiest way to learn this method is to go through an example. See the ...

First we need to list what we know from the text. Bob's speed : 13,48 mph and 6hour a day. The distance is 392,5 miles. How do we get the number of hours? Distance/Speed = 392,5/13,48 = 29,1172~ 29,12hour...

step 1: re-arrange the function in a nicer wayx = (y + 4)/44x = y + 4y = 4x - 4step 2: draw the graphthis is a stright line going through y axis at -4 and x axis at 1, with gradient of 4

There are multiple methods that be applied here to reach a solution, integration by substitution or by applying the basic rules of integration. The first step would be to expand the expression within the ...
