Simplifying 0 = b2 + -15b + -18819 Reorder the terms: 0 = -18819 + -15b + b2 Solving 0 = -18819 + -15b + b2 Solving for variable 'b'. Combine like terms: 0 + 18819 = 18819 18819 + 15b + -1b2 = -18819 + -15b + b2 + 18819 + 15b + -1b2 Reorder the terms: 18819 + 15b + -1b2 = -18819 + 18819 + -15b + 15b + b2 + -1b2 Combine like terms: -18819 + 18819 = 0 18819 + 15b + -1b2 = 0 + -15b + 15b + b2 + -1b2 18819 + 15b + -1b2 = -15b + 15b + b2 + -1b2 Combine like terms: -15b + 15b = 0 18819 + 15b + -1b2 = 0 + b2 + -1b2 18819 + 15b + -1b2 = b2 + -1b2 Combine like terms: b2 + -1b2 = 0 18819 + 15b + -1b2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -18819 + -15b + b2 = 0 Move the constant term to the right: Add '18819' to each side of the equation. -18819 + -15b + 18819 + b2 = 0 + 18819 Reorder the terms: -18819 + 18819 + -15b + b2 = 0 + 18819 Combine like terms: -18819 + 18819 = 0 0 + -15b + b2 = 0 + 18819 -15b + b2 = 0 + 18819 Combine like terms: 0 + 18819 = 18819 -15b + b2 = 18819 The b term is -15b. Take half its coefficient (-7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. -15b + 56.25 + b2 = 18819 + 56.25 Reorder the terms: 56.25 + -15b + b2 = 18819 + 56.25 Combine like terms: 18819 + 56.25 = 18875.25 56.25 + -15b + b2 = 18875.25 Factor a perfect square on the left side: (b + -7.5)(b + -7.5) = 18875.25 Calculate the square root of the right side: 137.38722648 Break this problem into two subproblems by setting (b + -7.5) equal to 137.38722648 and -137.38722648.Subproblem 1
b + -7.5 = 137.38722648 Simplifying b + -7.5 = 137.38722648 Reorder the terms: -7.5 + b = 137.38722648 Solving -7.5 + b = 137.38722648 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + b = 137.38722648 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + b = 137.38722648 + 7.5 b = 137.38722648 + 7.5 Combine like terms: 137.38722648 + 7.5 = 144.88722648 b = 144.88722648 Simplifying b = 144.88722648Subproblem 2
b + -7.5 = -137.38722648 Simplifying b + -7.5 = -137.38722648 Reorder the terms: -7.5 + b = -137.38722648 Solving -7.5 + b = -137.38722648 Solving for variable 'b'.
