-1/2 , 0 , 3/2
Step-by-step explanation:
Given equation is:
We know that![|x|=a\\The\ solution\ will\ be:\\x=a\ and\ x=-a\\](/tpl/images/0023/9200/cc86f.png)
So, from given equation,we will get two solutions:
x= ±√3/2 , 0
and
x= ±1/2 , 0
We can check that 1/2 and -3/2 do not satisfy the given equation.
So, 1/2 and -3/2 will not be the part of the solution ..
So, the solutions in increasing order are:
-1/2 , 0 , 3/2 ..

Step-by-step explanation:
We are given that an equation
We have to find the solution of given equation and arrange the solution in increasing order.
and
when x < 0
because![\mid x\mid =x when x 0](/tpl/images/0023/9200/995ea.png)
=-x when x < 0
Using identity![a^2-b^2=(a+b)(a-b)](/tpl/images/0023/9200/2fa7a.png)
When we substitute x=![\frac{1}{2}](/tpl/images/0023/9200/9cdae.png)
Hence,
is a not solution of given equation.
When substitute![x=\frac{-3}{2}](/tpl/images/0023/9200/54f10.png)
Hence,
is not a solution of given equation.
Substitute x=
in the given equation
Hence,
is a solution of given equation.
Substitute
in the given equation
Hence,
is a solution of given equation.
