Simplifying b2 + -1800b + 1619100 = 0 Reorder the terms: 1619100 + -1800b + b2 = 0 Solving 1619100 + -1800b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '-1619100' to each side of the equation. 1619100 + -1800b + -1619100 + b2 = 0 + -1619100 Reorder the terms: 1619100 + -1619100 + -1800b + b2 = 0 + -1619100 Combine like terms: 1619100 + -1619100 = 0 0 + -1800b + b2 = 0 + -1619100 -1800b + b2 = 0 + -1619100 Combine like terms: 0 + -1619100 = -1619100 -1800b + b2 = -1619100 The b term is -1800b. Take half its coefficient (-900). Square it (810000) and add it to both sides. Add '810000' to each side of the equation. -1800b + 810000 + b2 = -1619100 + 810000 Reorder the terms: 810000 + -1800b + b2 = -1619100 + 810000 Combine like terms: -1619100 + 810000 = -809100 810000 + -1800b + b2 = -809100 Factor a perfect square on the left side: (b + -900)(b + -900) = -809100 Can't calculate square root of the right side. The solution to this equation could not be determined.
