Question

(x⁸-2)(x⁴-1)-x¹²+2x⁴​

Answer 1

Объяснение:

1) (x³ - 2) (x⁴- 1) — x¹²+ 2x⁴=x¹² x³-2x^+2-x¹²+2x^=-x³+2

Answer 2

To simplify the expression, let's break it down step by step:

1. Rewrite the expression: (x⁸ - 2)(x⁴ - 1) - x¹² + 2x⁴

2. Expand the first bracket using the distributive property: (x⁸ - 2)(x⁴ - 1) = x⁸(x⁴) - x⁸(1) - 2(x⁴) + 2(1)

   Simplifying further: = x¹² - x⁸ - 2x⁴ + 2

3. Now, the expression becomes: x¹² - x⁸ - 2x⁴ + 2 - x¹² + 2x⁴

4. Combine like terms: (-x⁸ + x⁸) + (-2x⁴ + 2x⁴) + (x¹² - x¹²) + 2 = 0 + 0 + 0 + 2 = 2

Therefore, the simplified expression is 2.
