Solution for =(0.75-0.25a)*(0.5)*(0.25-0.25a) equation:


Simplifying
0 = (0.75 + -0.25a)(0.5)(0.25 + -0.25a)

Reorder the terms for easier multiplication:
0 = 0.5(0.75 + -0.25a)(0.25 + -0.25a)

Multiply (0.75 + -0.25a) * (0.25 + -0.25a)
0 = 0.5(0.75(0.25 + -0.25a) + -0.25a * (0.25 + -0.25a))
0 = 0.5((0.25 * 0.75 + -0.25a * 0.75) + -0.25a * (0.25 + -0.25a))
0 = 0.5((0.1875 + -0.1875a) + -0.25a * (0.25 + -0.25a))
0 = 0.5(0.1875 + -0.1875a + (0.25 * -0.25a + -0.25a * -0.25a))
0 = 0.5(0.1875 + -0.1875a + (-0.0625a + 0.0625a2))

Combine like terms: -0.1875a + -0.0625a = -0.25a
0 = 0.5(0.1875 + -0.25a + 0.0625a2)
0 = (0.1875 * 0.5 + -0.25a * 0.5 + 0.0625a2 * 0.5)
0 = (0.09375 + -0.125a + 0.03125a2)

Solving
0 = 0.09375 + -0.125a + 0.03125a2

Solving for variable 'a'.

Combine like terms: 0 + -0.09375 = -0.09375
-0.09375 + 0.125a + -0.03125a2 = 0.09375 + -0.125a + 0.03125a2 + -0.09375 + 0.125a + -0.03125a2

Reorder the terms:
-0.09375 + 0.125a + -0.03125a2 = 0.09375 + -0.09375 + -0.125a + 0.125a + 0.03125a2 + -0.03125a2

Combine like terms: 0.09375 + -0.09375 = 0.00000
-0.09375 + 0.125a + -0.03125a2 = 0.00000 + -0.125a + 0.125a + 0.03125a2 + -0.03125a2
-0.09375 + 0.125a + -0.03125a2 = -0.125a + 0.125a + 0.03125a2 + -0.03125a2

Combine like terms: -0.125a + 0.125a = 0.000
-0.09375 + 0.125a + -0.03125a2 = 0.000 + 0.03125a2 + -0.03125a2
-0.09375 + 0.125a + -0.03125a2 = 0.03125a2 + -0.03125a2

Combine like terms: 0.03125a2 + -0.03125a2 = 0.00000
-0.09375 + 0.125a + -0.03125a2 = 0.00000

Begin completing the square.  Divide all terms by
-0.03125 the coefficient of the squared term: 

Divide each side by '-0.03125'.
3 + -4a + a2 = 0

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -4a + -3 + a2 = 0 + -3

Reorder the terms:
3 + -3 + -4a + a2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -4a + a2 = 0 + -3
-4a + a2 = 0 + -3

Combine like terms: 0 + -3 = -3
-4a + a2 = -3

The a term is -4a.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4a + 4 + a2 = -3 + 4

Reorder the terms:
4 + -4a + a2 = -3 + 4

Combine like terms: -3 + 4 = 1
4 + -4a + a2 = 1

Factor a perfect square on the left side:
(a + -2)(a + -2) = 1

Calculate the square root of the right side: 1

Break this problem into two subproblems by setting 
(a + -2) equal to 1 and -1.

Subproblem 1

a + -2 = 1 Simplifying a + -2 = 1 Reorder the terms: -2 + a = 1 Solving -2 + a = 1 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + a = 1 + 2 Combine like terms: -2 + 2 = 0 0 + a = 1 + 2 a = 1 + 2 Combine like terms: 1 + 2 = 3 a = 3 Simplifying a = 3

Subproblem 2

a + -2 = -1 Simplifying a + -2 = -1 Reorder the terms: -2 + a = -1 Solving -2 + a = -1 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + a = -1 + 2 Combine like terms: -2 + 2 = 0 0 + a = -1 + 2 a = -1 + 2 Combine like terms: -1 + 2 = 1 a = 1 Simplifying a = 1

Solution

The solution to the problem is based on the solutions from the subproblems. a = {3, 1}
