Simplifying 4(x2 + 5) = 2(x2 + 1) Reorder the terms: 4(5 + x2) = 2(x2 + 1) (5 * 4 + x2 * 4) = 2(x2 + 1) (20 + 4x2) = 2(x2 + 1) Reorder the terms: 20 + 4x2 = 2(1 + x2) 20 + 4x2 = (1 * 2 + x2 * 2) 20 + 4x2 = (2 + 2x2) Solving 20 + 4x2 = 2 + 2x2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2x2' to each side of the equation. 20 + 4x2 + -2x2 = 2 + 2x2 + -2x2 Combine like terms: 4x2 + -2x2 = 2x2 20 + 2x2 = 2 + 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 20 + 2x2 = 2 + 0 20 + 2x2 = 2 Add '-20' to each side of the equation. 20 + -20 + 2x2 = 2 + -20 Combine like terms: 20 + -20 = 0 0 + 2x2 = 2 + -20 2x2 = 2 + -20 Combine like terms: 2 + -20 = -18 2x2 = -18 Divide each side by '2'. x2 = -9 Simplifying x2 = -9 Reorder the terms: 9 + x2 = -9 + 9 Combine like terms: -9 + 9 = 0 9 + x2 = 0 The solution to this equation could not be determined.
