Question

sum of roots of x²-16=0 is​

Answer 1

Answer:

4 wiil be the answer..

x=4

${4}^{2} - 16 = 16 - 16 = 0$

Answer 2

We have,

$\qquad \: {x}^{2} - 16 = 0 \\ \implies {(x)}^{2} - {(4)}^{2} = 0 \\ \implies(x - 4)(x + 4) = 0 \\ \implies(x - 4) = 0 \ \boxed{or} \qquad (x + 4) = 0 \\ \implies x = 4 \qquad \ \ \: \boxed{or} \implies x = - 4$
Thus, ( 4 ) and ( - 4 ) are the zeroes.

Hence,
$\sf \: sum \: \: of \: \: zeroes \\ = (4) + ( - 4) \\ = 4 - 4 \\ = \cancel{4} - \cancel{4} \\ = \bf0$
