identify all intercept and reasonable estimates of local maxima, and minima. identify the multiplicity of the factors
1) F(X)=(2X^2+2X-4)(X^2-6X+9)

2) F(X)=X^2(X+2)^2(X-5)

Which part exactly do you not understand?

Does the following provide any help?

$
F(X)=(2X^2+2X-4)(X^2-6X+9) =$
$2(X^2+X-2)(X^2-6X+9)= 2(X+2)(X-1)(X-3)^2
$

3. the local maxima and minima

4. Those are places where the derivative is 0. And you can use the product rule on the factor form pickslides gave you.
