Answer 2

The equation you provided is a polynomial equation, where x is the variable and the equation is set to equal zero:

x^3 + x^2 - x - 1 = 0

This is a third-degree polynomial equation, also known as a cubic equation, because the highest power of x is 3. To solve this equation, you can try to factor it, use numerical methods, or find approximate solutions using graphing techniques or calculators.

Unfortunately, finding exact solutions for most third-degree (and higher) polynomials is not always straightforward, as there is no general formula like there is for quadratic equations (up to degree 2). For some special cases, there are analytical methods to find the roots, but for more complex polynomials, numerical methods are often used.

If you are looking for approximate solutions, you can use a graphing calculator or software to plot the function and find where it crosses the x-axis (i.e., where the function equals zero). Alternatively, numerical methods like the Newton-Raphson method or bisection method can be used to approximate the roots. However, implementing these methods is beyond the scope of a simple text response.
