## Step 1 :

Isolate the square root on the left hand side :

## Step 2 :

Eliminate the radical ~ above the left hand next :

Raise both political parties to the 2nd power(√(25/4))2=(x)2After squaring (25/4)=x2

## Step 3 :

Rearranged equationx2-(25/4)=0This equation has two rational roots: x1,x2=5/2,-5/2

## Step 4 :

Check the the an initial solution is correct :

Original equation√(25/4)=xPlug in (5/2) because that x√(25/4)=(5/2)Simplify√6.25=2.5Solution check !!Solution is: x=(5/2)

## Step 5 :

Check that the second solution is correct :

Original equation√(25/4)=xPlug in -(5/2) for x√(25/4)=(-5/2)Simplify√6.25=-2.5Solution go not examine 2.5≠-2.5

## One equipment was found :

x=(5/2)
