To solve, “complete the square” in s µ s + b 2 a 2 µ b 2 a 2 + c a =0 Rewrite to leave only the term involving s on the left hand side µ s + b 2 a 2 = µ 1 2 a 2 ³ b 2 4 ac ´ Take the square root of each side to Fnd the solutions s 1 , 2 = b 2 a ± 1 2 a p b 2 4 ac There are two solutions, so it is necessary to rewrite the equation in a di±erent form to develop the Matlab commands. x = b 2 a y = b 2 4 ac 2 a s 1 = x + y s 2 = x y Matlab session: >> a=2;
