Simplifying f(2a) = 2a + -4 Remove parenthesis around (2a) f * 2a = 2a + -4 Reorder the terms for easier multiplication: 2f * a = 2a + -4 Multiply f * a 2af = 2a + -4 Reorder the terms: 2af = -4 + 2a Solving 2af = -4 + 2a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-2a' to each side of the equation. -2a + 2af = -4 + 2a + -2a Combine like terms: 2a + -2a = 0 -2a + 2af = -4 + 0 -2a + 2af = -4 Reorder the terms: 4 + -2a + 2af = -4 + 4 Combine like terms: -4 + 4 = 0 4 + -2a + 2af = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(2 + -1a + af) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(2 + -1a + af)' equal to zero and attempt to solve: Simplifying 2 + -1a + af = 0 Solving 2 + -1a + af = 0 Move all terms containing a to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -1a + -2 + af = 0 + -2 Reorder the terms: 2 + -2 + -1a + af = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1a + af = 0 + -2 -1a + af = 0 + -2 Combine like terms: 0 + -2 = -2 -1a + af = -2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
