@Michele_Laino please help me

OpenStudy (michele_laino):

please what is the minimum common denominator between \((x+2)\) and \((x+5)\)?

OpenStudy (michele_laino):

@goalieboy

OpenStudy (goalieboy):

yes I think that the answer is A

OpenStudy (michele_laino):

hint: since the minimum common denominator is \((x+2)\cdot(x+5)\), we can write this: \[\Large \begin{gathered} \frac{{2x}}{{x + 2}} - \frac{{x - 3}}{{x + 5}} = \hfill \\ \hfill \\ = \frac{{2x\left( {x + 5} \right) - \left( {x - 3} \right)\left( {x + 2} \right)}}{{\left( {x + 2} \right)\left( {x + 5} \right)}} = ...? \hfill \\ \end{gathered} \]

OpenStudy (goalieboy):

am I correct with A

OpenStudy (michele_laino):

yes! That's right! It is option A
