Answer:
Step-by-step explanation:
To get the equation, you must create the factors containing the roots.
So for example the first set of roots can be produced from
(x -2)(x^2 + 9)
which equals (when expanded) x^3 + 9x - 2x^2 - 18 which when put in the correct order gives
x^3 -2x^2 + 9x - 18
The second one is a bit more difficult to judge.
-5 and -3+ square root(2)
I don't think this is a polynomial. The coefficent is not integral. (-3 +√2)
(5 cases)/(2 3/8 hour)
(5 cases)/(19/8 hours)
(5*8/19) cases/hour....invert the fraction and multiply 1/(19/8 hour)=(8/19)/hour
40/19 cases/hour
2 2/19 cases/hour
