Simplifying 2(w2 + 3w + 20) = 0 Reorder the terms: 2(20 + 3w + w2) = 0 (20 * 2 + 3w * 2 + w2 * 2) = 0 (40 + 6w + 2w2) = 0 Solving 40 + 6w + 2w2 = 0 Solving for variable 'w'. Factor out the Greatest Common Factor (GCF), '2'. 2(20 + 3w + w2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(20 + 3w + w2)' equal to zero and attempt to solve: Simplifying 20 + 3w + w2 = 0 Solving 20 + 3w + w2 = 0 Begin completing the square. Move the constant term to the right: Add '-20' to each side of the equation. 20 + 3w + -20 + w2 = 0 + -20 Reorder the terms: 20 + -20 + 3w + w2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + 3w + w2 = 0 + -20 3w + w2 = 0 + -20 Combine like terms: 0 + -20 = -20 3w + w2 = -20 The w term is 3w. 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. 3w + 2.25 + w2 = -20 + 2.25 Reorder the terms: 2.25 + 3w + w2 = -20 + 2.25 Combine like terms: -20 + 2.25 = -17.75 2.25 + 3w + w2 = -17.75 Factor a perfect square on the left side: (w + 1.5)(w + 1.5) = -17.75 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
