Ignore the factor 25.
Subproblem 1
Set the factor 'x2' equal to zero and attempt to solve:

Simplifying
x2 = 0

Solving
x2 = 0

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

Simplifying
x2 = 0

Take the square root of each side:
x = {0}
Subproblem 2
Set the factor '(1 + -2x + 4x2)' equal to zero and attempt to solve:

Simplifying
1 + -2x + 4x2 = 0

Solving
1 + -2x + 4x2 = 0

Begin completing the square.  Divide all terms by
4 the coefficient of the squared term: 

Divide each side by '4'.
0.25 + -0.5x + x2 = 0

Move the constant term to the right:

Add '-0.25' to each side of the equation.
0.25 + -0.5x + -0.25 + x2 = 0 + -0.25

Reorder the terms:
0.25 + -0.25 + -0.5x + x2 = 0 + -0.25

Combine like terms: 0.25 + -0.25 = 0.00
0.00 + -0.5x + x2 = 0 + -0.25
-0.5x + x2 = 0 + -0.25

Combine like terms: 0 + -0.25 = -0.25
-0.5x + x2 = -0.25

The x term is -0.5x.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5x + 0.0625 + x2 = -0.25 + 0.0625

Reorder the terms:
0.0625 + -0.5x + x2 = -0.25 + 0.0625

Combine like terms: -0.25 + 0.0625 = -0.1875
0.0625 + -0.5x + x2 = -0.1875

Factor a perfect square on the left side:
(x + -0.25)(x + -0.25) = -0.1875

Can't calculate square root of the right side.
