Question

Find all rational root of the following function:
f(x)= -2x(x-6)(x+1)

Answer 1

f(x) = 0 -2x = 0 ; x- 6 = 0 ; x + 1 = 0

0, -1, 6

Answer 2

Can you explain how to find the rational roots?

Answer 3

0 is not rational

Answer 4

So would it just be 6 then?

Answer 5

0 is not rational

Answer 6

the roots are the values of x that make f(x) = 0
same as where the function/graph crosses the x-axis

Answer 7

if (x-a) is a factor then there is no remainder when x = a
