Which shows one way to determine the factors of x%5E3+%2B+11x%5E2+-+3x+-33 by grouping?
take a look on coefficients:
1%2Ax%5E3+-> prime, divisible by 1
11x%5E2->prime, divisible by 1 and 11
+-+3x+->prime, divisible by 1 and 3
-33 -> divisible by 1 ,3 and 33
so, the best way is to group those with common factors:
1%2Ax%5E3+ with -+3x
and
++11x%5E2 with -33

%28x%5E3+-+3x%29+%2B+%2811x%5E2+-33%29
x%28x%5E2+-+3%29+%2B+11%28x%5E2+-3%29
%28x+%2B+11%29%28x%5E2+-3%29
