Subproblem 1

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

Subproblem 2

Set the factor '(g + 2f)' equal to zero and attempt to solve: Simplifying g + 2f = 0 Reorder the terms: 2f + g = 0 Solving 2f + g = 0 Move all terms containing f to the left, all other terms to the right. Add '-1g' to each side of the equation. 2f + g + -1g = 0 + -1g Combine like terms: g + -1g = 0 2f + 0 = 0 + -1g 2f = 0 + -1g Remove the zero: 2f = -1g Divide each side by '2'. f = -0.5g Simplifying f = -0.5g

Solution

f = {0, -0.5g}
