Resposta ↓
Valor das raízes = {3, 2}
Explicação passo-a-passo:
Coeficiente a = valor acompanhado do x²
Coeficiente b = valor acompanhado do x
Coeficiente c = número sozinho
Coeficientes :
a = 1
b = - 5
c = 6
__________________________________________________________
Δ = b² - 4.a.c
Δ = (-5)² - 4.1.6
Δ = 25 - 24
Δ = 1
