I REALLY NEED HELP WITH THIS I HAVE NO CLUE WHAT IM DOING PLEASE HELP!!!!!!!!!!!!!

F(x)=9x^3+2x^2-5x+4 and g(x)=5x^3-7x+4. what is f(x)-g(x)? show all of your steps and write your final answer in factored form

Respuesta :

f(x)=9x³+2x²-5x+4
g(x)=5x³-7x+4

f(x)-g(x)=(9x³+2x²-5x+4)-(5x³-7x+4)=
=9x³+2x²-5x+4-5x³+7x-4=
=(9x³-5x³)+2x²+(-5x+7x)-4=
=4x³+2x²+2x-4

Answer; f(x)-g(x)=4x³+2x²+2x-4
