Hi guys. i’m not sure how to answer this so i was wondering if you guys could me.
question: what are the roots of the following polynomial x cubed - 9x?

how would i do this correctly? do a step by step answer.
!

x = 0, x = ± 3

Step-by-step explanation:

To find the roots equate the polynomial to zero, that is solve

x³ - 9x = 0 ← factor out x from both terms

x(x² - 9) = 0 ← factor difference of squares

x(x - 3)(x + 3) = 0

equate each factor to zero and solve for x

x = 0

x - 3 = 0 ⇒ x = 3

x + 3 = 0 ⇒ x = - 3

roots are x = 0, x = ± 3

what are ur choices?

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
