Question

Find the zeros of the polynomial function.

f(x) = x3 - 6x2 + 9x

***[isuru]*** · Answer

factorize it..this time it's ur turn.. :)


first take out a common factor.. u can take out "x" as the common factor ... wt will u get then ?

anonymous · Answer

3-6(2)+9?????  omg I dunno

***[isuru]*** · Answer

x [ x^2 - 6x + 9  ]

***[isuru]*** · Answer

now u can factorize the other parts
          x [  x^2 - 6x + 9 ]
            
       = x [ x^2 -3x - 3x + 9 ]

       = x[ x ( x -3 )  - 3( x -3 ) ]
 
        = x [ ( x-3) ( x-3) ]

ooooohhh I c I didn't put in the exponents the right way, hahaha its supposed to be x^3-6x^2+9x

***[isuru]*** · Answer

so... if the function is equal to zero
          x = 0  or  x= 3
which means
          zeros r 0 and 3
