Question

2^3+2x = 4^1-x^3-3x помогите!

Answer 1

8+2х=4-x^2-2x
2х+2х+х^2=4-8
4x+x^2=-4
x^2+4x+4=0
D=4^2-4*4*1=16-16=0 D=0
x=-4/2
x=-2

Answer 2

Solving the Equation

To solve the equation 2^3 + 2x = 4^1 - x^3 - 3x, we need to simplify and rearrange the terms to isolate the variable x. Let's break down the steps:

1. Start with the given equation: 2^3 + 2x = 4^1 - x^3 - 3x. 2. Simplify the exponents: 8 + 2x = 4 - x^3 - 3x. 3. Combine like terms: 2x + 3x = 4 - 8 - x^3. 4. Simplify further: 5x = -4 - x^3. 5. Rearrange the terms: x^3 + 5x + 4 = 0.

Now, we have a cubic equation that we can solve. Unfortunately, there is no simple algebraic method to solve cubic equations. We can use numerical methods or calculators to find the approximate solutions.
