Simplifying f(4x) = 4f(x) Remove parenthesis around (4x) f * 4x = 4f(x) Reorder the terms for easier multiplication: 4f * x = 4f(x) Multiply f * x 4fx = 4f(x) Multiply f * x 4fx = 4fx Add '-4fx' to each side of the equation. 4fx + -4fx = 4fx + -4fx Combine like terms: 4fx + -4fx = 0 0 = 4fx + -4fx Combine like terms: 4fx + -4fx = 0 0 = 0 Solving 0 = 0 Couldn't find a variable to solve for. This equation is an identity, all real numbers are solutions.
