Answer 1

x² - 6x+5=0

a = 1

b = -6

c = 5

x = -b ± √b² - 4ac / 2a

x = -(-6) ± √(-6)² - 4 (1) (5) / 2(1)

x = 6 ± √36 - 20 / 2

x = 6 ± √16 / 2

x = 6 ± 4 /2

x1 = 6 + 4/2 = 8

x2 = 6 - 4/2 = 4

x²-5x+6=0

a = 1

b = -5

c = 6

x = -b ± √b² - 4ac / 2a

x = -(-5) ± √(-5)² - 4 (1) (6) / 2(1)

x = 5 ± √25 - 24 / 2

x = 5 ± 1 /2

x1 = 5 + 1/2 = 11/2

x2 = 5 - 1/2 = 9/2

x²+2x+2=0

a = 1

b = 2

c = 2

x = -b ± √b² - 4ac / 2a

x = -2 ± √(2)² - 4 (1) (2) / 2(1)

x = -2 ± √4 - 8/2

x = -2 ± √-4/2

x²+x=0

a = 1

b = 1

x = -b ± √b² - 4ac / 2a

x = -1 ± √(1)² - 4 (1) (0) / 2(1)

x = -1 + √1 / 2

x = -1 ± 1/2

x1 = -1 + 1/2 = -1/2

x2 = -1 - 1/2 = -3/2
