And how do you find them? ;o
Is it just factoring and using the degree?

anonymous · Answer

X(2x^3-5x+6)-4    then solve it.

How would that find the zeros..?

lukecrayonz · Answer

OH wow. nevermind

lukecrayonz · Answer

No, wait, it wants me to find the possible number, not the actual zeros.

anonymous · Answer

these is 3 number let function = 0, x=0 is one, and other 2 is the answer of the 2x^3-5x+6=0
