Simplifying b2 = 6b + -16 Reorder the terms: b2 = -16 + 6b Solving b2 = -16 + 6b Solving for variable 'b'. Reorder the terms: 16 + -6b + b2 = -16 + 6b + 16 + -6b Reorder the terms: 16 + -6b + b2 = -16 + 16 + 6b + -6b Combine like terms: -16 + 16 = 0 16 + -6b + b2 = 0 + 6b + -6b 16 + -6b + b2 = 6b + -6b Combine like terms: 6b + -6b = 0 16 + -6b + b2 = 0 Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + -6b + -16 + b2 = 0 + -16 Reorder the terms: 16 + -16 + -6b + b2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -6b + b2 = 0 + -16 -6b + b2 = 0 + -16 Combine like terms: 0 + -16 = -16 -6b + b2 = -16 The b term is -6b. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6b + 9 + b2 = -16 + 9 Reorder the terms: 9 + -6b + b2 = -16 + 9 Combine like terms: -16 + 9 = -7 9 + -6b + b2 = -7 Factor a perfect square on the left side: (b + -3)(b + -3) = -7 Can't calculate square root of the right side. The solution to this equation could not be determined.
