The probability of choosing a multiple of -6 from this set is 3/7
<h3>How to determine the probability?</h3>
The set of even integers is given as:
A = {-18, -16, -14, ...... -6}
In the above set, we have:
Multiples of -6 = 3
Total element = 7
The probability of choosing a multiple of -6 from this set is then calculated as:
P= Multiples of -6/Total element
Substitute the known values in the above equation
P = 3/7
Hence, the probability of choosing a multiple of -6 from this set is 3/7

Your answer would be rational because that fraction is reasonable
Answer:
a = 1
Step-by-step explanation:
(x²+x-1)(x-1) = x³+x²-x-x²-x+1 = x³-2x+1
