Simplifying b2 + -12b + 64 = 0 Reorder the terms: 64 + -12b + b2 = 0 Solving 64 + -12b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '-64' to each side of the equation. 64 + -12b + -64 + b2 = 0 + -64 Reorder the terms: 64 + -64 + -12b + b2 = 0 + -64 Combine like terms: 64 + -64 = 0 0 + -12b + b2 = 0 + -64 -12b + b2 = 0 + -64 Combine like terms: 0 + -64 = -64 -12b + b2 = -64 The b term is -12b. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12b + 36 + b2 = -64 + 36 Reorder the terms: 36 + -12b + b2 = -64 + 36 Combine like terms: -64 + 36 = -28 36 + -12b + b2 = -28 Factor a perfect square on the left side: (b + -6)(b + -6) = -28 Can't calculate square root of the right side. The solution to this equation could not be determined.
