Question

x⁴ -25x²y² factorise​

Answer 1

x⁴ + 4

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)

= (x² - 2x +2) (x² + 2x + 2).

Answer 2

Answer:

Step-by-step explanation:

$x^{2} - 25x^{2} y^{2} \\(x^{2} + 5xy)(x^{2} - 5xy)$$[a^{2} - b^{2} = (a+b)(a-b)]$
