Simplifying b2 + -5b + -16 = -80 Reorder the terms: -16 + -5b + b2 = -80 Solving -16 + -5b + b2 = -80 Solving for variable 'b'. Reorder the terms: -16 + 80 + -5b + b2 = -80 + 80 Combine like terms: -16 + 80 = 64 64 + -5b + b2 = -80 + 80 Combine like terms: -80 + 80 = 0 64 + -5b + b2 = 0 Begin completing the square. Move the constant term to the right: Add '-64' to each side of the equation. 64 + -5b + -64 + b2 = 0 + -64 Reorder the terms: 64 + -64 + -5b + b2 = 0 + -64 Combine like terms: 64 + -64 = 0 0 + -5b + b2 = 0 + -64 -5b + b2 = 0 + -64 Combine like terms: 0 + -64 = -64 -5b + b2 = -64 The b term is -5b. 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. -5b + 6.25 + b2 = -64 + 6.25 Reorder the terms: 6.25 + -5b + b2 = -64 + 6.25 Combine like terms: -64 + 6.25 = -57.75 6.25 + -5b + b2 = -57.75 Factor a perfect square on the left side: (b + -2.5)(b + -2.5) = -57.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
