Question

Factorise the following x²+1-6/x²

Answer 1

Answer:

$\frac{x {}^{2} + 1 - 6}{x {}^{2} } = \frac{x {}^{2} - 5}{x {}^{2} } \\ = \frac{x {}^{2} }{ x{}^{2} } - \frac{5}{x {}^{2} } \\ = 1 - \frac{5}{x {}^{2} }$

Answer 2

Answer:

(x²+3)(x²-2)/x²

Step-by-step explanation:

x²+1-6/x²=

(x⁴+x²-6)/x²=

(x²+3)(x²-2)/x²
