Best ResponseYou've already chosen the best response.1x+ 5 or x5 might be a factor find f(5) and see if it = 0

Best ResponseYou've already chosen the best response.0we can factor out x^2 between the first two terms, and we can factor out 25x between the third and the fourth term, so we get this: \[\Large {x^3}  5{x^2}  25x + 125 = {x^2}\left( {x  5} \right)  25x\left( {x  5} \right)\]

Best ResponseYou've already chosen the best response.1OOOH  did you guess that?? (x5) is a factor because f(5) = 0

Best ResponseYou've already chosen the best response.0oops... we can factor out 25 between the third and the fourth terms, not 25 x: \[\Large {x^3}  5{x^2}  25x + 125 = {x^2}\left( {x  5} \right)  25\left( {x  5} \right)\]

Best ResponseYou've already chosen the best response.0So would the roots be 5,5,5 or 5,5,5?

Best ResponseYou've already chosen the best response.1the roots are 5 and 5 root 5 is a duplicate

Best ResponseYou've already chosen the best response.0Ok but since the polynomial is 3 there has to be 3 roots?

Best ResponseYou've already chosen the best response.1 correction  that was rubbish the roots are 5 , 5 and 5

Best ResponseYou've already chosen the best response.1yes 5 and 5 duplicity 2

Best ResponseYou've already chosen the best response.1factors are (x + 5)(x  5)(x  5) the fist gives x = 5 and the other 2 give x = 5

Best ResponseYou've already chosen the best response.1no 3 roots  because there are 2 5's
