Rearrange y ^ 4 - 4y ^ 3 + 6y ^ 2 - 4y + 2 = x ^ 5 + 7 to make y the subject.

To rearrange the equation \( y^4 - 4y^3 + 6y^2 - 4y + 2 = x^5 + 7 \) and solve for \( y \), we observe that this is a quartic (degree 4) equation in terms of \( y \), meaning it cannot be simply rearranged algebraically to express \( y \) as a simple function of \( x \).

The equation:

\[
y^4 - 4y^3 + 6y^2 - 4y + 2 = x^5 + 7
\]

is a polynomial of degree 4 in \( y \), and rearranging it to isolate \( y \) would typically require numerical methods or specific techniques for solving quartic equations (like Ferrari's method). However, there is no general closed-form expression for \( y \) in this case, since quartic equations can be quite complex and their solutions are not always expressible in a simple form.

In summary:
- There is no simple algebraic rearrangement for \( y \) in terms of \( x \).
- Solving for \( y \) would require numerical approximation methods, like Newton's method, depending on specific values of \( x \).

Would you like details on how to solve quartic equations or numerical methods to approximate \( y \) for specific \( x \)-values?
