посмотри ещё раз второй пример может ты его просто неправильно написала

Answer 2

Let's solve the equation step by step:

Step 1: Expand both sides of the equation. On the left-hand side (LHS): (x - 5)(x + 5) = x^2 - 5x + 5x - 25 = x^2 - 25

On the right-hand side (RHS): x(x - 4)(x - 9)(x - 9) - x^2 = x(x^2 - 9x - 4x + 36) - x^2 = x(x^2 - 13x + 36) - x^2 = x^3 - 13x^2 + 36x - x^2 = x^3 - 14x^2 + 36x

Step 2: Combine like terms on the right-hand side: RHS = x^3 - 14x^2 + 36x

Step 3: Set the two expressions equal to each other and form the equation: x^2 - 25 = x^3 - 14x^2 + 36x

Step 4: Move all terms to one side of the equation to set it to zero: x^3 - 14x^2 + 36x - x^2 - 25 = 0

Step 5: Combine like terms: x^3 - 15x^2 + 36x - 25 = 0

Now, we have a cubic equation. Solving cubic equations can be more involved than quadratic equations, but there are numerical methods to find approximate solutions. However, I cannot provide the exact solutions without a specific value of x or a more precise equation.

If you have a particular value of x or additional information, please provide it, and I'll be happy to assist you further.
