<h3>
Answer:</h3>
A, F
<h3>
Step-by-step explanation:</h3>
When the roots are a and b, the factors are (x-a) and (x-b). For roots -20 and 9, the factors are (x+20) and (x-9).
This selects answer A and eliminates choices B and C.
___
Multiplying the two factors gives ...
... (x +20)(x -9) = x² +11x -180
This selects answer F and eliminates choices D and E.
