3. what’s a polynomial function in standard form with zeros 1,2,-3, and -1? 4. what are the zeros of the function? what are their multiplicities? 5. what are the real and complex solutions of the polynomial equation?

Question 3. The polynomial function that  has roots 1, 2, -3 and -1 has factors (x-1), (x-2), (x+3) and (x+1), respectively. Then the form of this polynomial function is

correct choice is A

Question 4. Factor the polynomial function All three terms of the polynomial function have common factor then

Factor the quadratic function

then

This means that roots are -3, -2 and 0 of multiplicity 1.

correct choice is C

Question 5. The equation can be rewritten as

The quadratic equation has roots

The roots of the equation are

correct choice is C

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
