Método de factorización

One step at a time

13 x²−32 x+53 =0

Encontrar el mínimo común múltiplo de 3, 2: 6

Multiplicar por el mínimo común múltiplo=6

13 x²· 6−32 x· 6+53 · 6=0· 6

Simplificar

2x²−9x+10=0

Resolver con la fórmula general para ecuaciones de segundo grado:

x_{1, 2}=−(−9)± √(−9)²−4· 2· 102· 2

√(−9)²−4· 2· 10=1

x_{1, 2}=−(−9)± 12· 2

Separar las soluciones

x₁=−(−9)+12· 2 , x₂=−(−9)−12· 2

x=−(−9)+12· 2 : 52

x=−(−9)−12· 2 : 2

Las soluciones a la ecuación de segundo grado son:

x=52 , x=2
