Simplifying 2x2 + -8x + 22 = 0 Reorder the terms: 22 + -8x + 2x2 = 0 Solving 22 + -8x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(11 + -4x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(11 + -4x + x2)' equal to zero and attempt to solve: Simplifying 11 + -4x + x2 = 0 Solving 11 + -4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-11' to each side of the equation. 11 + -4x + -11 + x2 = 0 + -11 Reorder the terms: 11 + -11 + -4x + x2 = 0 + -11 Combine like terms: 11 + -11 = 0 0 + -4x + x2 = 0 + -11 -4x + x2 = 0 + -11 Combine like terms: 0 + -11 = -11 -4x + x2 = -11 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = -11 + 4 Reorder the terms: 4 + -4x + x2 = -11 + 4 Combine like terms: -11 + 4 = -7 4 + -4x + x2 = -7 Factor a perfect square on the left side: (x + -2)(x + -2) = -7 Can't calculate square root of the right side.
