f(x)= x^3+4x^2-10x12; x+6 Hi relichunter09, I assume the x between 10 and 12 is supposed to be a +. Use the Remainder theorem to see if f(-6)=0.
I suspect rather that the is supposed to be a "+" between the "x" and the 12. That is, that f(x)= x^3+4x^2-10x+ 12.
relichunter09, what is f(-6)? Do you see why I asked that?
F(x)= x^3+4x^2-10x+12; x+6 -6+6 = 0
F(-6)= -6^3+4(-6)^2-10(-6)+12 = 0
