To solve the equation \( x^2 + 2x^3 + 3x^4 = 100 \), we can approach it using numerical methods or by graphing. Let's use numerical methods to find an approximate solution.

The equation is:
\[ f(x) = x^2 + 2x^3 + 3x^4 - 100 = 0 \]

We can use a method such as Newton's method to find the roots of this equation. Let's proceed with that.

1. Define the function \( f(x) \) and its derivative \( f'(x) \).
2. Use an initial guess \( x_0 \) and apply the iterative formula for Newton's method: 
   \[ x_{n+1} = x_n - \frac{f(x_n)}{f'(x_n)} \]

Let's start with this process.

1. \( f(x) = x^2 + 2x^3 + 3x^4 - 100 \)
2. \( f'(x) = 2x + 6x^2 + 12x^3 \)

Now, we'll use an initial guess \( x_0 = 2 \).

Let me perform the calculations.The approximate solution to the equation \( x^2 + 2x^3 + 3x^4 = 100 \) using Newton's method is \( x \approx 2.222 \).
