Question

Pf me ajudem a fazer essa conta x² + 5x + 6 = 0 

Answer 1

x^2 + 5x + 6 = (x+2)(x+3) = 0
Logo as raizes são -2 e -3

Answer 2

Olá

x² + 5x + 6 = 0

a= 1

b= 5

c= 6

Calculando delta

Δ = b² - 4.a.c

Δ = 5² - 4. 1. 6

Δ = 25 - 24

Δ = 1

Aplicando Bhaskara

x = - b +- √Δ / 2.a

x' = - b + √1/2.1

x' = - 5 + 1/2

x' = - 4/2

x' = - 2

x" = - 5 - √1/2.1

x" = - 5 - 1/2

x" = - 6/2

x" = - 3

S = {x' = - 2 e x" = - 3}

Bons estudos
