Simplifying -2x2 + -8x + -170 = 0 Reorder the terms: -170 + -8x + -2x2 = 0 Solving -170 + -8x + -2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-2'. -2(85 + 4x + x2) = 0 Ignore the factor -2.Subproblem 1
Set the factor '(85 + 4x + x2)' equal to zero and attempt to solve: Simplifying 85 + 4x + x2 = 0 Solving 85 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-85' to each side of the equation. 85 + 4x + -85 + x2 = 0 + -85 Reorder the terms: 85 + -85 + 4x + x2 = 0 + -85 Combine like terms: 85 + -85 = 0 0 + 4x + x2 = 0 + -85 4x + x2 = 0 + -85 Combine like terms: 0 + -85 = -85 4x + x2 = -85 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 = -85 + 4 Reorder the terms: 4 + 4x + x2 = -85 + 4 Combine like terms: -85 + 4 = -81 4 + 4x + x2 = -81 Factor a perfect square on the left side: (x + 2)(x + 2) = -81 Can't calculate square root of the right side.
