Answer:

x = {-0.8, 0.8}

Step-by-step explanation:

Simplifying

25x2 = 16

Solving

25x2 = 16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '25'.

x2 = 0.64

Simplifying

x2 = 0.64

Take the square root of each side:

x = {-0.8, 0.8}
