Question

Find the zeros of the polynomial function.

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

Answer 1

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 ?

Answer 2

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

Answer 3

x [ x^2 - 6x + 9 ]

Answer 4

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) ]

Answer 5

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

Answer 6

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

Answer 7

yup.....ur so right! :D
