Question

14. Find the zeroes of the following polynomial :
5V5x2 + 30x + 815​

Answer 1

Answer:

$\sqrt[5]{5} \times 2 + 30x + 815$

$( \sqrt[5]{5} )2 + 30x + 815$

$\sqrt[5]{5} \times \sqrt[5]{5} + 30x + 815$

$5 \times 5 \times 5 + 30x + 815$

$125 + 30x + 815$

$815 + 125 = - 30x$

$940 = - 30x$

$x = 940 \div - 30$

$x = 31.33$
