Simplifying -1x2 + -5x + -18 = 0 Reorder the terms: -18 + -5x + -1x2 = 0 Solving -18 + -5x + -1x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-1'. -1(18 + 5x + x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(18 + 5x + x2)' equal to zero and attempt to solve: Simplifying 18 + 5x + x2 = 0 Solving 18 + 5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + 5x + -18 + x2 = 0 + -18 Reorder the terms: 18 + -18 + 5x + x2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + 5x + x2 = 0 + -18 5x + x2 = 0 + -18 Combine like terms: 0 + -18 = -18 5x + x2 = -18 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 = -18 + 6.25 Reorder the terms: 6.25 + 5x + x2 = -18 + 6.25 Combine like terms: -18 + 6.25 = -11.75 6.25 + 5x + x2 = -11.75 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = -11.75 Can't calculate square root of the right side.
