... that a 0 (2. 3) For later reference, it is useful to rewrite the last two equalities in a different form. Equation (2. 2) is the same as x b (2. 4) and equation (2. 3) is the same as x 0 (2. 5) where a ... sides b , c , and b c yields b c b c b c and from equation (2. 8) we obtain b b c c b c b b c c b c Canceling equal terms and dividing by -2 yields the desired result. Corollary...
