(3/x)+[13/(x-11)]
I got -28 for the answer but didn't know if it was right
?? Is there a value for x?
no just to simplify.
its 3 over x + 13 over x-11 and I am just supposed to simplify.
given \[\frac{ 3 }{ x } + \frac{13}{x-11}\] we can multiply any term by 1, right? We want a common denominator, so try multiplying each term by a version of 1... \[\frac{x-11}{x-11}\] and \[\frac{x}{x}\] respectively to see what happens.
I did that and after everything i got -28
If you don't have a value for x your answer should still include x. When you multiplied (x-11)/(x-11) and x/x what did you end up with?
3x-33 over x^2-11x + 13x over x^2-11x
would that be it or could i simplify more.
Perfect. Now that you have a common denominator, you can combine your two fractions into one, combining like terms in your numerator: [(3x-33)+13x]/(x^2-11x)
oh okay, so in the end it would be 16x-33 over x^2-11x?
exactly! That's as simple as you can get. :) Good work
