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 '(7b + 2a)' equal to zero and attempt to solve: Simplifying 7b + 2a = 0 Reorder the terms: 2a + 7b = 0 Solving 2a + 7b = 0 Move all terms containing a to the left, all other terms to the right. Add '-7b' to each side of the equation. 2a + 7b + -7b = 0 + -7b Combine like terms: 7b + -7b = 0 2a + 0 = 0 + -7b 2a = 0 + -7b Remove the zero: 2a = -7b Divide each side by '2'. a = -3.5b Simplifying a = -3.5b

Subproblem 3

Set the factor '(-7b + 2a)' equal to zero and attempt to solve: Simplifying -7b + 2a = 0 Reorder the terms: 2a + -7b = 0 Solving 2a + -7b = 0 Move all terms containing a to the left, all other terms to the right. Add '7b' to each side of the equation. 2a + -7b + 7b = 0 + 7b Combine like terms: -7b + 7b = 0 2a + 0 = 0 + 7b 2a = 0 + 7b Remove the zero: 2a = 7b Divide each side by '2'. a = 3.5b Simplifying a = 3.5b

Solution

a = {0, -3.5b, 3.5b}
