Simplifying 2x2 + -4x + 40 = 0 Reorder the terms: 40 + -4x + 2x2 = 0 Solving 40 + -4x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(20 + -2x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(20 + -2x + x2)' equal to zero and attempt to solve: Simplifying 20 + -2x + x2 = 0 Solving 20 + -2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-20' to each side of the equation. 20 + -2x + -20 + x2 = 0 + -20 Reorder the terms: 20 + -20 + -2x + x2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + -2x + x2 = 0 + -20 -2x + x2 = 0 + -20 Combine like terms: 0 + -20 = -20 -2x + x2 = -20 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 = -20 + 1 Reorder the terms: 1 + -2x + x2 = -20 + 1 Combine like terms: -20 + 1 = -19 1 + -2x + x2 = -19 Factor a perfect square on the left side: (x + -1)(x + -1) = -19 Can't calculate square root of the right side.
