Simplifying 2x2 + -6x = -20 Reorder the terms: -6x + 2x2 = -20 Solving -6x + 2x2 = -20 Solving for variable 'x'. Reorder the terms: 20 + -6x + 2x2 = -20 + 20 Combine like terms: -20 + 20 = 0 20 + -6x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(10 + -3x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(10 + -3x + x2)' equal to zero and attempt to solve: Simplifying 10 + -3x + x2 = 0 Solving 10 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-10' to each side of the equation. 10 + -3x + -10 + x2 = 0 + -10 Reorder the terms: 10 + -10 + -3x + x2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -3x + x2 = 0 + -10 -3x + x2 = 0 + -10 Combine like terms: 0 + -10 = -10 -3x + x2 = -10 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = -10 + 2.25 Reorder the terms: 2.25 + -3x + x2 = -10 + 2.25 Combine like terms: -10 + 2.25 = -7.75 2.25 + -3x + x2 = -7.75 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = -7.75 Can't calculate square root of the right side.
