Subproblem 1

Set the factor 'a' equal to zero and attempt to solve: Simplifying a = 0 Solving a = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a = 0

Subproblem 2

Set the factor '(4 + -2a + a2)' equal to zero and attempt to solve: Simplifying 4 + -2a + a2 = 0 Solving 4 + -2a + a2 = 0 Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + -2a + -4 + a2 = 0 + -4 Reorder the terms: 4 + -4 + -2a + a2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -2a + a2 = 0 + -4 -2a + a2 = 0 + -4 Combine like terms: 0 + -4 = -4 -2a + a2 = -4 The a term is -2a. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2a + 1 + a2 = -4 + 1 Reorder the terms: 1 + -2a + a2 = -4 + 1 Combine like terms: -4 + 1 = -3 1 + -2a + a2 = -3 Factor a perfect square on the left side: (a + -1)(a + -1) = -3 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Solution

a = {0}
