13) 9 over 4 × 4 over 3
9 × 4 over 4 × 3
36 over 12 = 3 over 1
Therefore, your answer would be 3 over 1
14) 7 over 5 × 20 over 9
7 × 20 over 5 × 9
140 over 45 = 3 and 1 over 9
Therefore, your answer would have to be: 3 and 1 over 9.

Answer:
k.
Step-by-step explanation:
The general form of a polynomial is: x² + bx + c = 0. Substituting the roots,
3² + b(3) + c = 0
3b + c = -9 --> eqn 1
(5 + √5)² + (5 +√5)(b) + c = 0
(5+√5)b + c = -30-10√5 --> eqn 2
Solving both equations simultaneously by subtracting eqn 2 from eqn 1,
(-2 - √5)b = 21 + 10√5
b = -8 - √5
Using eqn 1,
3(-8 - √5) + c = -9
-24 - 3√5 + c = -9
c = -9 + 24 + 3√5
c = 15 + 3√5
Hence, the polynomial is: <em>f(x) = x² + (-8 - √5)x + (15 + 3√5)</em>.
