Step by step solution :
Step 1 :
Isolate the square source on the left hand next :Radical currently isolated √(16/25)=x
Step 2 :
Eliminate the radical on the left hand next :Raise both political parties to the second power(√(16/25))2=(x)2After squaring (16/25)=x2
Step 3 :
Solve the quadratic equation :Rearranged equationx2(16/25)=0This equation has actually two reasonable roots: x1,x2=4/5,4/5
Step 4 :
Check that the an initial solution is exactly :Original equation√(16/25)=xPlug in (4/5) for x√(16/25)=(4/5)Simplify√0.64=0.8Solution check !!Solution is: x=(4/5)
Step 5 :
Check that the 2nd solution is exactly :Original equation√(16/25)=xPlug in (4/5) for x√(16/25)=(4/5)Simplify√0.64=0.8Solution go not examine 0.8≠0.8
