2 ^ (x ^ 2 - 3x - 10) = 3 ^ (x ^ 2 - 3x - 10)

To solve the equation \( 2^{x^2 - 3x - 10} = 3^{x^2 - 3x - 10} \), let's analyze the situation step by step.

### Step 1: Analyze the Equation
We have:
\[
2^{x^2 - 3x - 10} = 3^{x^2 - 3x - 10}
\]
Since the bases (2 and 3) are different, the only way these two expressions can be equal is if the exponent \( x^2 - 3x - 10 \) equals zero.

### Step 2: Set the Exponent Equal to Zero
Let's solve for \( x \) by setting the exponent equal to zero:
\[
x^2 - 3x - 10 = 0
\]

### Step 3: Solve the Quadratic Equation
This is a quadratic equation, and we can solve it using the quadratic formula:
\[
x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
\]
Here, \( a = 1 \), \( b = -3 \), and \( c = -10 \). Plugging in these values:
\[
x = \frac{-(-3) \pm \sqrt{(-3)^2 - 4(1)(-10)}}{2(1)}
\]
\[
x = \frac{3 \pm \sqrt{9 + 40}}{2}
\]
\[
x = \frac{3 \pm \sqrt{49}}{2}
\]
\[
x = \frac{3 \pm 7}{2}
\]
This gives us two possible solutions:
\[
x = \frac{3 + 7}{2} = 5
\]
\[
x = \frac{3 - 7}{2} = -2
\]

### Step 4: Verify the Solutions
To confirm, let's substitute \( x = 5 \) and \( x = -2 \) back into the original equation.

1. **For \( x = 5 \):**
   \[
   2^{5^2 - 3(5) - 10} = 2^{25 - 15 - 10} = 2^0 = 1
   \]
   \[
   3^{5^2 - 3(5) - 10} = 3^{25 - 15 - 10} = 3^0 = 1
   \]
   The equation holds true.

2. **For \( x = -2 \):**
   \[
   2^{(-2)^2 - 3(-2) - 10} = 2^{4 + 6 - 10} = 2^0 = 1
   \]
   \[
   3^{(-2)^2 - 3(-2) - 10} = 3^{4 + 6 - 10} = 3^0 = 1
   \]
   The equation holds true.

### Final Answer:
The solutions to the equation are \( x = 5 \) and \( x = -2 \).
