Best ResponseYou've already chosen the best response.2\[\large\rm \frac{ k^2+8k+12 } { 9k^2 + 15k +54} * \frac{k^2 +9k} { k^2 +7k +10}\] factor all qudratic equation so you can cancel out some stuff do you know how to factor quadratic equations ?

Best ResponseYou've already chosen the best response.2alright k is common k^2 can be written as k times k \[\huge\rm k \times \color{ReD}{k} + 9\color{Red}{k}\] k is common so it out \[\large\rm \color{ReD}{k}(k+9)\]

Best ResponseYou've already chosen the best response.2\[\large\rm \frac{ k^2+8k+12 } { 9k^2 + 15k +54} * \frac{\color{Red}{k(k+9)}} { k^2 +7k +10}\] now can you factor quadratic equations k^2 +8k +12 ?

Best ResponseYou've already chosen the best response.2i made a typo .. :P \[\large\rm \frac{ k^2+8k+12 } { k^2 + 15k +54} * \frac{\color{Red}{k(k+9)}} { k^2 +7k +10}\] here is it k^2 +15k +54 ?? denominator of first fraction ?

Best ResponseYou've already chosen the best response.2\[ \huge\rm \frac{(k+6) (k+2)}{(k+6) (k+9) }* \frac{ k (x+9) }{ (k+5) (k+2)} \] cancel!

Best ResponseYou've already chosen the best response.2\[ \huge\rm \frac{\cancel{(k+6)} \cancel{ (k+2)}}{\cancel{(k+6)} \cancel{\cancel{(k+9)}} }* \frac{ k \cancel{(x+9)} }{ (k+5) \cancel{(k+2)}} \] \[\large\rm \frac{ k }{ k+2 }\] yep right!
