Simplifying 2x2 + -10x + 20 = 0 Reorder the terms: 20 + -10x + 2x2 = 0 Solving 20 + -10x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(10 + -5x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(10 + -5x + x2)' equal to zero and attempt to solve: Simplifying 10 + -5x + x2 = 0 Solving 10 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-10' to each side of the equation. 10 + -5x + -10 + x2 = 0 + -10 Reorder the terms: 10 + -10 + -5x + x2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -5x + x2 = 0 + -10 -5x + x2 = 0 + -10 Combine like terms: 0 + -10 = -10 -5x + x2 = -10 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -10 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -10 + 6.25 Combine like terms: -10 + 6.25 = -3.75 6.25 + -5x + x2 = -3.75 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = -3.75 Can't calculate square root of the right side.
