Solve the equations 1. 16x^2-1=0 2. 36z^2 96z 15=0

Allisa [31]

$16x^2-1=0 2$

$16x^2-1=0 2:x$

$
16x^2=1
 
$ $|Add \ 1 \ to \ both \ sides|$

$x^2= \dfrac{1}{16}$ $|Divide \ both \ sides \ by \ 16|$ <span>
</span>
$x^2= \sqrt{\dfrac{ \sqrt{1}}{ \sqrt{16}}}$ $|Take \ the \ square \ root \ of \ both \ sides|$

$x= \dfrac{1}{4}$
