Best ResponseYou've already chosen the best response.1restrictions on values of 'x' right ?

Best ResponseYou've already chosen the best response.1Yes I already simplified it and multiplied it together, and this is the end product. But I don't know the restrictions bc it's a complex denominator.

Best ResponseYou've already chosen the best response.1complex denominator ? denominator = 5 (3x1)^2 right ? restrictions : denominator = 0 so, ''x can't take values for which denominator = 5 (3x1)^2 = 0 so, 3x1 = 0 can you solve this for x ?

Best ResponseYou've already chosen the best response.1Oh, so it's 1/3, but what about the 5? And would you write the final answernumerator like 4x^2x+4x1, or (x+1)(4x1)?

Best ResponseYou've already chosen the best response.1about the 5 : \(5 (3x1)^2=0 \\ \) divide both sides by 5 , 0/5 = 0 \((3x1)^2=0\) take square root, 3x1 = 0 x=1/3 is the restriction. numerator is a polynomial , so in this case it does not play any role.
