Question

X (x^2-2)=x^3+8 пожалуйста,помогите мне!

Answer 1

Х^3 -2х = х ^3 +8 -2х= 8 Х= -4

Answer 2

X^3-2x=x^3+8
X^3-x^3-2x=8
-2x=8
X=-4

Answer 3

Solving the Equation X(x^2-2)=x^3+8

To solve the equation X(x^2-2)=x^3+8, we can start by expanding the left-hand side and simplifying the equation.

Expanding the left-hand side of the equation: X(x^2-2) = Xx^2 - 2X

Now, the equation becomes: Xx^2 - 2X = x^3 + 8

To solve for X, we need to rearrange the terms and bring all terms to one side of the equation.

Subtracting Xx^2 from both sides: -2X = x^3 - Xx^2 + 8

Rearranging the terms: x^3 - Xx^2 - 2X - 8 = 0

Now, we have a cubic equation in terms of X and x. Solving this equation for X would involve complex algebraic manipulations and potentially the use of numerical methods or software.
