Simplifying -2x2 + -4x = 5 Reorder the terms: -4x + -2x2 = 5 Solving -4x + -2x2 = 5 Solving for variable 'x'. Reorder the terms: -5 + -4x + -2x2 = 5 + -5 Combine like terms: 5 + -5 = 0 -5 + -4x + -2x2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(5 + 4x + 2x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(5 + 4x + 2x2)' equal to zero and attempt to solve: Simplifying 5 + 4x + 2x2 = 0 Solving 5 + 4x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 2.5 + 2x + x2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + 2x + -2.5 + x2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + 2x + x2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + 2x + x2 = 0 + -2.5 2x + x2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 2x + x2 = -2.5 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = -2.5 + 1 Reorder the terms: 1 + 2x + x2 = -2.5 + 1 Combine like terms: -2.5 + 1 = -1.5 1 + 2x + x2 = -1.5 Factor a perfect square on the left side: (x + 1)(x + 1) = -1.5 Can't calculate square root of the right side.
