abx^2=(a-b)^2(x+1)

Solución

ab x^{2} = (a - b)^{2} (x + 1)

Solución

x = \frac{a - b}{b}, x = \frac{- a + b}{a}; ab \neq = 0

Pasos de solución

ab x^{2} = (a - b)^{2} (x + 1)

Desarrollar

(a - b)^{2} (x + 1) : a^{2} x + a^{2} - 2 ab x - 2 ab + b^{2} x + b^{2}

ab x^{2} = a^{2} x + a^{2} - 2 ab x - 2 ab + b^{2} x + b^{2}

Restar

b^{2} x + b^{2}

de ambos lados

ab x^{2} - (b^{2} x + b^{2}) = a^{2} x + a^{2} - 2 ab x - 2 ab + b^{2} x + b^{2} - (b^{2} x + b^{2})

Simplificar

ab x^{2} - b^{2} x - b^{2} = a^{2} x + a^{2} - 2 ab x - 2 ab

Restar

- 2 ab x - 2 ab

de ambos lados

ab x^{2} - b^{2} x - b^{2} - (- 2 ab x - 2 ab) = a^{2} x + a^{2} - 2 ab x - 2 ab - (- 2 ab x - 2 ab)

Simplificar

ab x^{2} - b^{2} x - b^{2} + 2 ab x + 2 ab = a^{2} x + a^{2}

Restar

a^{2} x + a^{2}

de ambos lados

ab x^{2} - b^{2} x - b^{2} + 2 ab x + 2 ab - (a^{2} x + a^{2}) = a^{2} x + a^{2} - (a^{2} x + a^{2})

Simplificar

ab x^{2} + (- b^{2} + 2 ab - a^{2}) x - b^{2} + 2 ab - a^{2} = 0

Resolver con la fórmula general para ecuaciones de segundo grado:

x_{1, 2} = \frac{- ( - b ^{2} + 2 ab - a ^{2} ) \pm ( - b ^{2} + 2 ab - a ^{2} ) ^{2} - 4 ab ( - b ^{2} + 2 ab - a ^{2} )}{2 ab}

Simplificar

(- b^{2} + 2 ab - a^{2})^{2} - 4 ab (- b^{2} + 2 ab - a^{2}) : (a + b) (a - b)

x_{1, 2} = \frac{- ( - b ^{2} + 2 ab - a ^{2} ) \pm ( a + b ) ( a - b )}{2 ab}; ab \neq = 0

Separar las soluciones

x_{1} = \frac{- ( - b ^{2} + 2 ab - a ^{2} ) + ( a + b ) ( a - b )}{2 ab}, x_{2} = \frac{- ( - b ^{2} + 2 ab - a ^{2} ) - ( a + b ) ( a - b )}{2 ab}

x = \frac{- ( - b ^{2} + 2 ab - a ^{2} ) + ( a + b ) ( a - b )}{2 ab} : \frac{a - b}{b}

x = \frac{- ( - b ^{2} + 2 ab - a ^{2} ) - ( a + b ) ( a - b )}{2 ab} : \frac{- a + b}{a}

Las soluciones a la ecuación de segundo grado son:

x = \frac{a - b}{b}, x = \frac{- a + b}{a}; ab \neq = 0
