estimate the local maxima and minima and identify the mulltiplicity of the factors. 1) F(X)=X^2(x+2)^2(X-5)

Your function has zeros at Min and Max points can be found between these points. Also note are repeated factors, do you know what this means?
no
Look at a graph of y= x and of y= x^2. Where there is a single root, the graph crosses the axis, so the function changes sign. Where there is a double root, the graph does not cross the graph and there is no change of sign.
