Additional maths O level (chapter polynomial)Hi everyone, #2 20140121 09:05:44
Re: Additional maths O level (chapter polynomial)hi righen or why not say you have solved ie y = 2, 4 and 3. I've made a new variable so I can use x as the variable in the second part. If you put y = 5x in the above you get which simplifies to which is the second question. So it must have solutions y = 2, y = 4 and y = 3 which becomes 5x = 2, 5x = 4 and 5x = 3 These will give three new values for x as answers. Let's try out just one of these to make sure this is working. I'll take the third one. If 5x = 3 then x = 3/5 Try in the equation and So LHS = RHS and we have a solution. I'll leave you to work out the other two for yourself. Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #3 20140121 09:26:23

and it helps that I've done loads of similar ones over the years. But it's still the same problem. Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei
