Question

Obtain zeroes of the polynomial

$( \: x {}^{2} - \: 5 \: )$
Find relationship between zeroes and co efficient

Answer 1

$answ \: is \: \: \: \: \: \: \: \ \ + \sqrt{5 } \: and \: - \sqrt{5}$

Answer 2

HOLA

========================

$f \: ( \: x \: ) \: = \: ( \: x {}^{2} - \: 5 \: ) \: = \: ( \: x {}^{2} - \: \sqrt{5} {}^{2} ) \: = \: ( x\: \: + \: \: \sqrt{5} ) \: \: + \: ( \: x \: - \: \sqrt{5} ) \\ \\ x \: = \: \sqrt{5} \: \: x \: = \: - \: \sqrt{5} \\ \\ \alpha \: + \: \beta \: = \: \sqrt{5} + \: - \: \sqrt{5} = \: \frac{0}{1} \\ \\ \\ \alpha \beta \: = \: \sqrt{5} \: \: \times \: - \: \sqrt{5} = \: \frac{5}{1}$
