Question

I need help with problems involving the square root property.
(5x-1)^2=4/25

Answer 1

Get rid of the squared on both sides of the equation by square rooting both sides.
- this will give you 5x-1= +2/5 or 5x-1 = -2/5

Add 1 to both sides of the equation.
- This will give you 5x= 7/5 or 5x= 3/5

Divide both sides of the equation by 5 (or I usually multiply by the inverse; 1/5 in this case).
- This will give you the answer: x= 7/25 or x=3/25

Answer 2

Thanks! That really helped.
