How about factoring?
f(x) = 2x3 – 9x + 3.

just factor

LAgrange!! PLEASE help.

saifoo.khan · Answer

the real problem is how to find the zeros of this equation and we have to explain that in steps.

saifoo.khan · Answer

i mean in sentences.

anonymous · Answer

sentences

saifoo.khan · Answer

i dont need solutions, just HOW TO/

anonymous · Answer

I set the function to zero
Then i factored and got two terms.
Next i applied the zero product property and i found the roots, by that i mean that i set each term term to zero and solved for x

jamesj · Answer

Are you sure it's 2x^3 – 9x + 3?  The roots are nasty.  but suppose they are r1, r2, r3, then of course

2x^3 – 9x + 3 = 2(x-r1)(x-r2)(x-r3)

saifoo.khan · Answer

Yes that's this. :/

anonymous · Answer

You probably should try finding the roots by using some numerical methods, which will give you approximated values of the roots.

anonymous · Answer

If I were you, I would start by plotting the polynomial to help me have a general view of the function and where the zeros might be. Then, I would use a method like Newton's method to approximate the roots.

now saifoo can do this he is smart =)

I am sure he is!
