Watch the utube video first.

Simplify the equation.

Using calculator, u will get only the answer,
$Z = \frac{5}{4}$ $Z= 5/4$
But u need to change it equal to zero. So,

$4 z = 5$ $4z = 5$

$4 z - 5 = 0$ $4z-5=0$
And factorize it. (Refer to the pic)

Hope this will help u.
If u hv any question, feel free to ask! :)
