Question

(x-1) (1+x+x²+x³) find the volue​

Answer 1

Answer:

⇢ x⁴ - 1

Step-by-step explanation:

⇢ (x - 1) (1 + x + x² + x³)

⇢ (x + -1) (1 + x + x² + x³)

⇢ (x)(1) + (x)(x) + (x)(x²) + (x)(x³) + (-1)(1) + (-1)(x) + (-1)(x²) + (-1)(x³)

⇢ x + x² + x³ + x⁴ - 1 - x - x² - x3

⇢ x⁴ - 1

Therefore, this is the required answer.
