Answer 2

To solve the equation, I assume you meant:

х - 1/2 = 4 + 2х^3

First, we need to isolate the variable "x" on one side of the equation. Here's the step-by-step solution:

Step 1: Combine the "x" terms on one side: х - 2х^3 - 1/2 = 4

Step 2: Bring all the terms to one side: -2х^3 + х - 4 + 1/2 = 0

Step 3: Get rid of the fraction by multiplying the entire equation by 2: -4х^3 + 2х - 8 + 1 = 0

Step 4: Simplify the equation: -4х^3 + 2х - 7 = 0

Now, this is a cubic equation, and solving cubic equations can be more involved than linear or quadratic equations. There are several methods to solve cubic equations, such as Cardano's method, but it can get quite lengthy.

If you're looking for the numerical solution, you can use numerical methods or calculators that can handle equations with numerical values. However, if you need the exact analytical solution, it might be best to use a computer algebra system like Mathematica or symbolic computation software to get the precise answer.

Keep in mind that due to the complexity of the equation, it's possible that it doesn't have an easily expressible exact solution in terms of elementary functions. In such cases, approximations or numerical methods are usually employed.
