Question

The zeros of the polynomial p(x) = 3x2 - 1 are
​

Answer 1

$3 {x}^{2} - 1 = 0$

${( \sqrt{3}x) }^{2} - {(1)}^{2} = 0$

$( \sqrt{3} x - 1)( \sqrt{3} x + 1) = 0$

$( \sqrt{3} x - 1) = 0$

$( \sqrt{3} x + 1) = 0$

$\sqrt{3} x = 1$

$\sqrt{3} x = - 1$

$x = \frac{1}{ \sqrt{3} }$

$x = \frac{ - 1}{ \sqrt{3} }$
