a) x2 + 5x + 6 = 0
a = 1, b = 5, c = 6
x1 + x2 = -b/a = -5/1 = -5
x1 . x2 = c/a = 6/1 = 6
b) 3x2 - 2x + 1 = 0
a = 3, b = -2, c = 1
x1 + x2 = -b/a = -(-2)/3 = 2/3
x1 . x2 = c/a = 1/3
c) ax2 - (a+2)x - a = 0
a = a, b = -(a+2) , c = -a
x1 + x2 = -b/a = -(-(a + 2))/a = (a+2)/a
x1 . x2 = c/a = -a/a = -1
