Simplifying -5b2 + -4b + -8 = 0 Reorder the terms: -8 + -4b + -5b2 = 0 Solving -8 + -4b + -5b2 = 0 Solving for variable 'b'. Factor out the Greatest Common Factor (GCF), '-1'. -1(8 + 4b + 5b2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(8 + 4b + 5b2)' equal to zero and attempt to solve: Simplifying 8 + 4b + 5b2 = 0 Solving 8 + 4b + 5b2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 1.6 + 0.8b + b2 = 0 Move the constant term to the right: Add '-1.6' to each side of the equation. 1.6 + 0.8b + -1.6 + b2 = 0 + -1.6 Reorder the terms: 1.6 + -1.6 + 0.8b + b2 = 0 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + 0.8b + b2 = 0 + -1.6 0.8b + b2 = 0 + -1.6 Combine like terms: 0 + -1.6 = -1.6 0.8b + b2 = -1.6 The b term is 0.8b. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8b + 0.16 + b2 = -1.6 + 0.16 Reorder the terms: 0.16 + 0.8b + b2 = -1.6 + 0.16 Combine like terms: -1.6 + 0.16 = -1.44 0.16 + 0.8b + b2 = -1.44 Factor a perfect square on the left side: (b + 0.4)(b + 0.4) = -1.44 Can't calculate square root of the right side.
