Question

3x3 + 9x2 + x + 3

Answer 1

33+x should be the answer

Answer 2

for the equation
\[3x ^{3}+9x ^{2}+x+3\] you can factor out a 3x^2 out of the first two parts so
\[3x ^{2}(x+3) + (x+3)\] then you can factor out (x+3) to get
\[(x+3)(3x ^{2}+1)\] then you can probably get your answer from there :)
