According to the task you give: <span>The binomial (y − 2) is a factor of y2 − 10y + 16. The other factor is C- (y-8) reffering to the major rules identifying the factors of binimials. By knowing factors you can make the factored form then by multiplying them.</span>
That is 3 slots
12 in 1st slot
11 in 2nd
10 in 3rd
so that is 12*11*10 or 1320 ways
The answer that you should get 35as^2-30s
