Simplifying 4b2 + b + -19 = 0 Reorder the terms: -19 + b + 4b2 = 0 Solving -19 + b + 4b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -4.75 + 0.25b + b2 = 0 Move the constant term to the right: Add '4.75' to each side of the equation. -4.75 + 0.25b + 4.75 + b2 = 0 + 4.75 Reorder the terms: -4.75 + 4.75 + 0.25b + b2 = 0 + 4.75 Combine like terms: -4.75 + 4.75 = 0.00 0.00 + 0.25b + b2 = 0 + 4.75 0.25b + b2 = 0 + 4.75 Combine like terms: 0 + 4.75 = 4.75 0.25b + b2 = 4.75 The b term is b. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.25b + 0.25 + b2 = 4.75 + 0.25 Reorder the terms: 0.25 + 0.25b + b2 = 4.75 + 0.25 Combine like terms: 4.75 + 0.25 = 5 0.25 + 0.25b + b2 = 5 Factor a perfect square on the left side: (b + 0.5)(b + 0.5) = 5 Calculate the square root of the right side: 2.236067978 Break this problem into two subproblems by setting (b + 0.5) equal to 2.236067978 and -2.236067978.Subproblem 1
b + 0.5 = 2.236067978 Simplifying b + 0.5 = 2.236067978 Reorder the terms: 0.5 + b = 2.236067978 Solving 0.5 + b = 2.236067978 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + b = 2.236067978 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + b = 2.236067978 + -0.5 b = 2.236067978 + -0.5 Combine like terms: 2.236067978 + -0.5 = 1.736067978 b = 1.736067978 Simplifying b = 1.736067978Subproblem 2
b + 0.5 = -2.236067978 Simplifying b + 0.5 = -2.236067978 Reorder the terms: 0.5 + b = -2.236067978 Solving 0.5 + b = -2.236067978 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + b = -2.236067978 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + b = -2.236067978 + -0.5 b = -2.236067978 + -0.5 Combine like terms: -2.236067978 + -0.5 = -2.736067978 b = -2.736067978 Simplifying b = -2.736067978Solution
