What is the simplified form of the quantity of x plus 5, all over the quantity of 9 − the quantity of x plus 4, all over the quantity of x plus 6?

Respuesta :

[tex]\bf \cfrac{x+5}{9}-\cfrac{x+4}{x+6}\impliedby \textit{our LCD is clearly 9(x+6)} \\\\\\ \cfrac{\underline{(x+6)}(x+5)~~-~~\underline{(9)}(x+4)}{9(x+6)} \implies \cfrac{\stackrel{FOIL}{x^2+11x+30}~~-~~[9x+36]}{9(x+6)} \\\\\\ \cfrac{x^2+11x+30~~-~~9x-36}{9(x+6)}\implies \cfrac{x^2+2x-6}{9(x+6)}[/tex]

The answer above is the correct answer
