a)x1 = -5 - √225 /2·10 = -5 - 15/ 20 = -20/ 20 = -1
x2 = -5 + √225/2·10 = -5 + 15 /20 = 10/ 20 = 0.5
b)x = -12 /2·(-2) = 3
v)x1 = 2 - √20 /2·1 = 1 - √5 ≈ -1.2360679774997898
x2 = 2 + √20 /2·1 = 1 + √5 ≈ 3.23606797749979
g)x1 = 0 - √576 2·12 = 0 - 24 /24 = -24 /24 = -1
x2 = 0 + √576 2·12 = 0 + 24/ 24 = 24 /24 = 1
