6x sq.-5x-1=0

use the equation of the squre if u want to solve it.

use the quadratic formula

how can i do fractons and i need some advised

First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where is more likely to be overlooked.

I searched Google under the key words "math fractions" to get these possible sources:

http://www.kidsolr.com/math/fractions.html

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.

To solve the equation 6x^2 - 5x - 1 = 0, we can use the quadratic formula.

The quadratic formula is given by x = (-b ± √(b^2 - 4ac)) / (2a), where a, b, and c are the coefficients of the equation ax^2 + bx + c = 0.

For the equation 6x^2 - 5x - 1 = 0, we have a = 6, b = -5, and c = -1.

Plugging these values into the quadratic formula, we get:

x = (5 ± √((-5)^2 - 4(6)(-1))) / (2(6))

Simplifying further:

x = (5 ± √(25 + 24)) / 12
x = (5 ± √(49)) / 12
x = (5 ± 7) / 12

This gives us two solutions:

x = (5 + 7) / 12 = 12 / 12 = 1

and

x = (5 - 7) / 12 = -2 / 12 = -1/6

Therefore, the solutions to the equation 6x^2 - 5x - 1 = 0 are x = 1 and x = -1/6.

To solve the equation 6x^2 - 5x - 1 = 0 using the quadratic formula, you can follow these steps:

Step 1: Identify the coefficients a, b, and c in the equation. In this case, a = 6, b = -5, and c = -1.

Step 2: Write down the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Step 3: Substitute the values of a, b, and c into the quadratic formula:

x = (-(-5) ± √((-5)^2 - 4(6)(-1))) / (2(6))

Simplifying this expression further:

x = (5 ± √(25 + 24)) / 12

x = (5 ± √49) / 12

Step 4: Simplify the square root:

x = (5 ± 7) / 12

Step 5: Split the equation into two solutions:

x₁ = (5 + 7) / 12 = 12 / 12 = 1

x₂ = (5 - 7) / 12 = -2 / 12 = -1/6

Therefore, the solutions to the equation 6x^2 - 5x - 1 = 0 are x = 1 and x = -1/6.
