Simplifying 0.2b2 + 15b + -150 = 0 Reorder the terms: -150 + 15b + 0.2b2 = 0 Solving -150 + 15b + 0.2b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 0.2 the coefficient of the squared term: Divide each side by '0.2'. -750 + 75b + b2 = 0 Move the constant term to the right: Add '750' to each side of the equation. -750 + 75b + 750 + b2 = 0 + 750 Reorder the terms: -750 + 750 + 75b + b2 = 0 + 750 Combine like terms: -750 + 750 = 0 0 + 75b + b2 = 0 + 750 75b + b2 = 0 + 750 Combine like terms: 0 + 750 = 750 75b + b2 = 750 The b term is 75b. Take half its coefficient (37.5). Square it (1406.25) and add it to both sides. Add '1406.25' to each side of the equation. 75b + 1406.25 + b2 = 750 + 1406.25 Reorder the terms: 1406.25 + 75b + b2 = 750 + 1406.25 Combine like terms: 750 + 1406.25 = 2156.25 1406.25 + 75b + b2 = 2156.25 Factor a perfect square on the left side: (b + 37.5)(b + 37.5) = 2156.25 Calculate the square root of the right side: 46.435439053 Break this problem into two subproblems by setting (b + 37.5) equal to 46.435439053 and -46.435439053.Subproblem 1
b + 37.5 = 46.435439053 Simplifying b + 37.5 = 46.435439053 Reorder the terms: 37.5 + b = 46.435439053 Solving 37.5 + b = 46.435439053 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-37.5' to each side of the equation. 37.5 + -37.5 + b = 46.435439053 + -37.5 Combine like terms: 37.5 + -37.5 = 0.0 0.0 + b = 46.435439053 + -37.5 b = 46.435439053 + -37.5 Combine like terms: 46.435439053 + -37.5 = 8.935439053 b = 8.935439053 Simplifying b = 8.935439053Subproblem 2
b + 37.5 = -46.435439053 Simplifying b + 37.5 = -46.435439053 Reorder the terms: 37.5 + b = -46.435439053 Solving 37.5 + b = -46.435439053 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-37.5' to each side of the equation. 37.5 + -37.5 + b = -46.435439053 + -37.5 Combine like terms: 37.5 + -37.5 = 0.0 0.0 + b = -46.435439053 + -37.5 b = -46.435439053 + -37.5 Combine like terms: -46.435439053 + -37.5 = -83.935439053 b = -83.935439053 Simplifying b = -83.935439053Solution
