To solve the quadratic equation \( 7x^2 + 11x = 6 \), we follow these steps:

### Step 1: Set the equation to zero
First, move all terms to one side of the equation:
\[
7x^2 + 11x - 6 = 0
\]

### Step 2: Apply the quadratic formula
The quadratic formula is:
\[
x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
\]
In this case, \(a = 7\), \(b = 11\), and \(c = -6\).

### Step 3: Calculate the discriminant
\[
\text{Discriminant} = b^2 - 4ac = 11^2 - 4(7)(-6)
\]
\[
\text{Discriminant} = 121 + 168 = 289
\]

### Step 4: Solve for \(x\)
Now, substitute the values into the quadratic formula:
\[
x = \frac{-11 \pm \sqrt{289}}{2(7)}
\]
\[
x = \frac{-11 \pm 17}{14}
\]

This gives us two possible solutions for \(x\):
1. \(x_1 = \frac{-11 + 17}{14} = \frac{6}{14} = \frac{3}{7}\)
2. \(x_2 = \frac{-11 - 17}{14} = \frac{-28}{14} = -2\)

### Final Answer
The solutions are:
\[
x = \frac{3}{7} \quad \text{or} \quad x = -2
\]
