Best ResponseYou've already chosen the best response.0\[ \frac{ 3x + 12x + 9 }{ x^2  4 } \div \frac{ 4x + 4 }{ x + 2 }\]

Best ResponseYou've already chosen the best response.0Because this is division, you have to flip the 2nd fraction and change it to multiplication. \[\frac{ 3x + 12x + 9 }{ x^2  4 } \times \frac{ x+2 }{ 4x+4 }\] You have to solve for the restrictions to find numbers that are NOT restrictions. The restrictions are any numbers that make the denominator 0. So you have to solve these two equations to get the restrictions \(x^24=0\) and \(4x+4=0\)

Best ResponseYou've already chosen the best response.0no, you can always test your options in the denominators. If you get 0, it's a restriction

Best ResponseYou've already chosen the best response.0does the number have to be same to be the restriction to both?

Best ResponseYou've already chosen the best response.0not necessarily. each fraction will have it's own restriction. The restrictions for the whole problem will be all of them combined
