Question

Quanto é o valor de delta e sua raiz?
6x²-x-5=0

Answer 1

Answer:

$\implies \: \boxed{x = 1 \: , \frac{ - 5}{6} }$

Step-by-step explanation:

According to the question-

$\implies \: 6 {x}^{2} - x - 5 = 0 \\ \\ \implies \: 6 {x}^{2} - 6x + 5x - 5 = 0 \\ \\ \implies \: 6x(x - 1) + 5(x - 1) = 0 \\ \\ \implies \: (x - 1)(6x + 5) = 0$

1. Case (1)

If ,x - 1 = 0

x = 1

2. Case (2)

If ,6x + 5 = 0

6x= -5

x = -5/6
