Step-by-step explanation

Absolute value basically measures how far the number is from zero,for example


\lvert x\rvert

as we can see


\lvert x\rvert=\lvert-x\rvert

hence,

Step 1


\lvert x\rvert=0

so, we need to find a number such the distance from zero to that number be zero,

therefore , that number is zero

hence


\begin{gathered} x_1=0 \\ x_2=0 \end{gathered}

Step 2


\lvert x\rvert=2

now, weed to find a value such distance from zero is 2, so those values are +2 and -2


\begin{gathered} x_1=2 \\ x_2=-2 \end{gathered}

Step 3

c)


\lvert x\rvert=-6

the solution of a absolute value function is always positive, remeber we are talking about a distance, so, there is not solutioni


\begin{gathered} c) \\ x_1=DNE \\ x_2=\text{DNE} \end{gathered}

I hope this helps you
