Simplify the following:
14/(a^12) - 2 b^2
Put each term in 14/(a^12) - 2 b^2 over the common denominator a^12: 14/(a^12) - 2 b^2 = 14/a^12 - (2 a^12 b^2)/a^12:
14/a^12 - (2 a^12 b^2)/a^12
14/a^12 - (2 a^12 b^2)/a^12 = (14 - 2 a^12 b^2)/a^12:
(14 - 2 a^12 b^2)/a^12
Factor 2 out of 14 - 2 a^12 b^2:
Answer: (2 (7 - a^12 b^2))/a^12
