Best ResponseYou've already chosen the best response.1If a polynomial f(x) is divided by (xa) then (xa) is a factor of f(x) if f(a)=0

Best ResponseYou've already chosen the best response.0so as per factor therom you get x+1.

Best ResponseYou've already chosen the best response.0I don't see how the factor theorem can help with this question (x^2 + 7x – 44) though?

Best ResponseYou've already chosen the best response.1Did u get for 2x^2 + 16x – 18

Best ResponseYou've already chosen the best response.0I got it but i'm not sure exactly how you worked it out i tried and got stuck

Best ResponseYou've already chosen the best response.1f(x)=2x^2+16x18 Now, U need to try for every options for which u will get f(a)=0 when it is divided by (xa)

Best ResponseYou've already chosen the best response.1In this case, When f(x) is divided by (x+9), f(9)=2*(9)^2+16*(9)18=0

Best ResponseYou've already chosen the best response.1So, one of the factor of f(x) is (x+9)
