Question

factorize x^{4}-16 pleaseeeee any one immediatly answer the question

Answer 1

Answer:

hope my answer helps you..

Answer 2

Answer: (x² + 4)(x + 2)(x - 2)

Explanation:

x⁴ - 16

= (x²)² - (4)²

[a² - b² = (a + b)(a - b)]

= (x² + 4)(x² - 4)

= (x² + 4)[(x)² - (2)²]

= (x² + 4)(x + 2)(x - 2)

More:

• (a ± b)² = a² + b² ± 2ab
• (x + a)(x + b) = x² + (a + b)x + ab
• (a + b + c)² = a² + b² + c² + 2(ab + bc + ca)
• a² - b² = (a + b)(a - b)
• 4ab = (a + b)² - (a - b)²
• 2(a² + b²) = (a + b)² + (a - b)²
• (a ± b)³ = a³ ± b³ ± 3ab(a ± b)
• a³ - b³ = (a - b)(a² + ab + b²)
• a³ + b³ = (a + b)(a² - ab + b²)
• a³ + b³ + c³ - 3abc = (a + b + c)(a² + b² + c² - ab - bc - ca)
