Question

write factors of x^4 ‐ x​

Answer 1

Answer:

Hello Mate!

x⁴ + 4

= (x² + 2)² - 4x²

= (x² + 2)² - (2x)²

a² - b² = (a + b)(a - b)

= (x² + 2 + 2x)(x² + 2 - 2x)

Answer : (x² + 2 + 2x)(x² + 2 - 2x)

Answer 2

Answer:

x4−x2−12=(x−2)(x+2)(x2+ 3). Explanation: Use the difference of squares identity: a2−b2=(a−b)(a+b). with a=x and b=2 ...
