Question

Ecuacion de segundo grado x^2+3bx-1b^2=0

Answer 1

Respuesta:

x1 = (-3b + b√13) / 2

x2 = (-3b - b√13) / 2

Explicación:

x²+ 3bx - b² = 0

x = (-b±√b²-4ac)/2a

x = (-3b±√(3b)²-4(1)(-b²))/2(1)

x = (-3b±√9b²+4b²))/2

x = (-3b±√13b²))/2

x = (-3b±b√13))/2

x1 = (-3b + b√13) / 2

x2 = (-3b - b√13) / 2
