expand

(a + 2) (3 a^{2} + 12) (a - 2)

3 a^{4} - 48

Solution steps

(a + 2) (3 a^{2} + 12) (a - 2)

Expand

(a + 2) (3 a^{2} + 12) (a - 2) : (a^{2} - 4) (3 a^{2} + 12)

= (a^{2} - 4) (3 a^{2} + 12)

Apply FOIL method

(a^{2} - 4) (3 a^{2} + 12) : 3 a^{4} - 48

= 3 a^{4} - 48

\frac{3}{8} - \frac{1}{4} + \frac{5}{6}
