Solve the equation by square root method 16x^2-25=0

The value of x is 5/4 or -5/4

Step-by-step explanation:

It is given that,

16x² - 25 = 0

This is a quadratic equation, x have 2 values.

To solve the equation by square root method

16x² - 25 = 0

16x² = 25  

(4x)² = 5²

Taking square root on both the sides. We get,

√(4x)² = √5²

4x = ± 5

4x = +5 or 4x = -5

If 4x = +5

x = 5/4

if 4x = -5

x = -5/4

Therefore the value of x is 5/4 or -5/4
