Question

Soluciona la siguiente ecuacion se la forma ax²+bx+c=0

1- 2x²+x-3=0


2- 3x²+x-1=0​

Answer 1

Respuesta:

1) x1 = -3/2 ^ x2 = 1

2) x1 = (-1-√13)/6 ^ x2 = (-1+√13)/6

Explicación paso a paso:

1) 2x² + x - 3 = 0

2x +3

x -1

=> (2x+3)(x-1) = 0

=> 2x + 3 = 0 ^ x - 1 = 0

=> x = -3/2 ^ x = 1

2) 3x² + x - 1 = 0 ,fórmula general: -b±√(b²-4ac)/2a

x = (-1 ± √(1²-4(3)(-1)))/2(3)

x = (-1 ± √13)/6

=> x1 = (-1-√13)/6

=> x2 = (-1+√13)/6
