Expert Solution
Step 1

Graphically, we know that roots of a function are those points on x-axis where graph of the function either cuts the x-axis or touches it.

If graph of function fx cuts the x-axis at points x=a (let's say) , then x-a is a factor of the function fx

If graph of function fx touches the x-axis at points x=b (let's say), then x-b2 is a factor of the function fx.
