## saifoo.khan 4 years ago How about factoring? f(x) = 2x3 – 9x + 3.

• This Question is Closed
1. LagrangeSon678

just factor

2. saifoo.khan

LAgrange!! PLEASE help.

3. saifoo.khan

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

4. saifoo.khan

i mean in sentences.

5. LagrangeSon678

sentences

6. saifoo.khan

i dont need solutions, just HOW TO/

7. LagrangeSon678

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

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)

9. saifoo.khan

Yes that's this. :/

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

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!
