Prime factorization of

12 : 2 \cdot 2 \cdot 3

Prime factorization of

20 : 2 \cdot 2 \cdot 5

Prime factorization of

30 : 2 \cdot 3 \cdot 5

Compute a number comprised of factors that appear in at least one of the following:

\frac{1}{2}, \frac{1}{6}, \frac{1}{12}, \frac{1}{20}, \frac{1}{30}

= 2 \cdot 2 \cdot 3 \cdot 5

Multiply the numbers:

= 60

x^{3} + 4 x^{2} + 5 x - 2, (111)

1 + x + x^{2}, 1 - x - x^{2}, 1 - x^{2}

\frac{( 3 x - 5 )}{( x - 4 )}

\frac{( x + 1 )}{( x - 1 )}

\frac{( 3 x ^{2} - 2 x ^{3} - 1 )}{( x + 2 )}
