Question

11) RESOLVA A EQUAÇÃO X2 - 5x + 6 =0 USANDO A FÓRMULA DE BHASKARA.​

Answer 1

x² - 5x + 6 = 0

a = 1

b = -5

c = 6

Δ = b²- 4 . a . c

Δ = (-5)² - 4 . 1 . 6

Δ = 25 - 24

Δ = 1

x = -b ± √Δ /2 . a

x = -(-5) ± √1 /2 . 1

x = 5 ± 1 /2

x' = 5 - 1 /2

x' = 4/2

x' = 2

x" = 5 + 1 /2

x" = 6/2

x" = 3

S = { 2 , 3 }

Answer 2

Resposta:

A= 1

B= -5

C= 6

∆= b² - 4.a.c

∆= (-5)² - 4.1.6

∆= 25 - 24

∆= 1

X= -b ± √∆/2a

X= - (-5) ± √1/2.1

X¹= 5 +1/2

X¹= 6/2

X¹= 3

X²= 5-1/2

X²= 4/2

X²= 2
