Question 1099268: A) Factor the Polynomial Completely
P(x)= x^3 - 3x^2 + 4x
B) Find all its zeros. State the multiplicity of each zero. (order your answers from smallest to largest real, followed by complex answers ordered smallest to largest real part, then smallest to largest imaginary part)

x^3 - 3x^2 + 4x , factor out an x
x(x^2-3x+4)=0
x=0 is one root.
quadratic formula for other two
x=(1/2)(3+/- sqrt (9-16)), so roots are 0, (1/2)(3- i sqrt(7)) and (1/2) (3+ i sqrt(7)). Each is multiplicity 1
