Weba2 = b2 + c2 – 2bc x cos (α) b² = a² + c² - 2ac x cos (β) c² = a² + b² - 2ab x cos (γ) The formula can also differ if you have a right triangle. Its angle between the a and b leg is 90 degrees – with a cosine of 0. In this instance, you reduce the formula to a Pythagorean theorem. a² = b² + c² - 2bc x cos (90°) a² = b² + c² Web2bc 2bc • a 2 2bc = ——— = ———————— 1 a 2 Trying to factor by pulling out : 12.2 Factoring: a 4 + 2a 3 b - 2a 2 b 2 - 4a 2 c 2 - 2ab - 2bc Thoughtfully split the expression at hand into groups, each group having two terms : Group 1: -4a 2 c 2 + a 4 Group 2: 2a 3 b - 2a 2 b 2 Group 3: -2ab - 2bc
