Question

resolve into factor x⁴+4​

Answer 1

Step-by-step explanation:

x^4+2^2

= (x^2)^2 +2^2

= (x^2+2)^2 - 4x^2

Answer 2

Answer:

Step-by-step explanation:

Add and subtract 4x²,

= x⁴ + 4x² +4 - 4x²

= (x²)² + 2(2)(x²) + 2² - 4x²

= (x² +2)² - 4x²

= (x² +2)² - (2x)²

= (x² + 2 - 2x) (x² + 2 + 2x)
