ZEROS OF POLYNOMIAL FUNCTIONS I. MODIFIED TRUE OR FALSE DIRECTION: Write TRUE if the statement is correct. If not, change the underline word to make the statement correct. NO ERASURE OR ANY ALTERATION ON EVERY FINAL ANSWER. For number 1 – 4, refer to the illustration of synthetic division.
_________1. The depressed polynomial is x^2+4x+3. ______2. In P(x)=x^{3-2x2-21x-18,} (x-6) is a binomial factor. ______3. The complete factorization of the function as illustrated in the synthetic division above is f(x)=(x+6)(x+3)(x+1). ______4. The zeros of the function are -6,-3,and-1. ______5. The list of possible zeros in f(x)=4x^3+4x2-x-1 can be obtained using rational zero theorem. For number 6 – 7 If a polynomial function has integer coefficients, then every rational zero of the function has the form p/q, where p is the factor of the (6) constant term and q is the factor of (7) the leading coefficient term. ______________________6.
_________________________7.
II. COMPUTATION DIRECTION: Do as directed. SHOW YOUR SOLUTION. NO SOLUTION, NO SCORE! NO ERASURE OR ANY ALTERATION OF THE FINAL ANSWER.

What do YOU think?
While we're happy to help we will not do all the work for you.

1. "Explain your reasoning".
2. So you expect us to do this for you? And you get the credit?
