5.1 Explain why the "if" direction is true, i.e. why it's true that if fix1 has a factor x k, then [The \"only if" direction is harder.1 11 Now let's use the theorem to factor a polynomial. Use your calculator to nd the zeros of 1:3 3s1 s + 3 {graph and find the zeros by eye or use 2nd CAL: zero}. 3.1 Once you have found the zeros, what are some factors? [In this case, these are all the factors.1 9.1 Let's loolt at dividing a polynomial by a non-factor. If f{z1 = s1 + 1': - 5, and you divide by I -2, what is the quotient and remainder? 1D.1 Notice the 2 in our diyisor {z - 21 for #9. What is HI}? 11.1 Mal-Le a conjecture for the Remainder Theorem: if a polynomial fix} is divided by I k, the remainder is
