Best ResponseYou've already chosen the best response.2cal the unknown number 'x'. then what the question states is:\[x+\frac{8}{x}=6\]do you know how to solve this?

Best ResponseYou've already chosen the best response.2first multiply both sides of the equation by 'x' to get rid of the fraction. this gives us:\[x^2+8=6x\]which can be rearranged to:\[x^26x+8=0\]this is a standard quadratic equation. hopefully you know how to solve this?

Best ResponseYou've already chosen the best response.2ok  looks like you are trying to solve a problem without first learning the foundation behind it. It might be better for you to first review any notes that your teacher may have given you and then try again to solve this. The aim of OpenStudy is to help students understand how to solve problems  not just give them the answer.

Best ResponseYou've already chosen the best response.2ok  that is the correct approach. you confused me above by saying that ou didn't know how to factorise.

Best ResponseYou've already chosen the best response.2I guess what you were trying to say is that you know how to factorise but just couldn't "see" what the factors were for this problem?
