Simplifying 3 = 5x2 + 2x + 18 Reorder the terms: 3 = 18 + 2x + 5x2 Solving 3 = 18 + 2x + 5x2 Solving for variable 'x'. Combine like terms: 3 + -18 = -15 -15 + -2x + -5x2 = 18 + 2x + 5x2 + -18 + -2x + -5x2 Reorder the terms: -15 + -2x + -5x2 = 18 + -18 + 2x + -2x + 5x2 + -5x2 Combine like terms: 18 + -18 = 0 -15 + -2x + -5x2 = 0 + 2x + -2x + 5x2 + -5x2 -15 + -2x + -5x2 = 2x + -2x + 5x2 + -5x2 Combine like terms: 2x + -2x = 0 -15 + -2x + -5x2 = 0 + 5x2 + -5x2 -15 + -2x + -5x2 = 5x2 + -5x2 Combine like terms: 5x2 + -5x2 = 0 -15 + -2x + -5x2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(15 + 2x + 5x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(15 + 2x + 5x2)' equal to zero and attempt to solve: Simplifying 15 + 2x + 5x2 = 0 Solving 15 + 2x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 3 + 0.4x + x2 = 0 Move the constant term to the right: Add '-3' to each side of the equation. 3 + 0.4x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + 0.4x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 0.4x + x2 = 0 + -3 0.4x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 0.4x + x2 = -3 The x term is 0.4x. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4x + 0.04 + x2 = -3 + 0.04 Reorder the terms: 0.04 + 0.4x + x2 = -3 + 0.04 Combine like terms: -3 + 0.04 = -2.96 0.04 + 0.4x + x2 = -2.96 Factor a perfect square on the left side: (x + 0.2)(x + 0.2) = -2.96 Can't calculate square root of the right side. 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.
