Simplifying (30 + -1x) * x = 36 Reorder the terms for easier multiplication: x(30 + -1x) = 36 (30 * x + -1x * x) = 36 (30x + -1x2) = 36 Solving 30x + -1x2 = 36 Solving for variable 'x'. Reorder the terms: -36 + 30x + -1x2 = 36 + -36 Combine like terms: 36 + -36 = 0 -36 + 30x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 36 + -30x + x2 = 0 Move the constant term to the right: Add '-36' to each side of the equation. 36 + -30x + -36 + x2 = 0 + -36 Reorder the terms: 36 + -36 + -30x + x2 = 0 + -36 Combine like terms: 36 + -36 = 0 0 + -30x + x2 = 0 + -36 -30x + x2 = 0 + -36 Combine like terms: 0 + -36 = -36 -30x + x2 = -36 The x term is -30x. Take half its coefficient (-15). Square it (225) and add it to both sides. Add '225' to each side of the equation. -30x + 225 + x2 = -36 + 225 Reorder the terms: 225 + -30x + x2 = -36 + 225 Combine like terms: -36 + 225 = 189 225 + -30x + x2 = 189 Factor a perfect square on the left side: (x + -15)(x + -15) = 189 Calculate the square root of the right side: 13.747727085 Break this problem into two subproblems by setting (x + -15) equal to 13.747727085 and -13.747727085.Subproblem 1
x + -15 = 13.747727085 Simplifying x + -15 = 13.747727085 Reorder the terms: -15 + x = 13.747727085 Solving -15 + x = 13.747727085 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '15' to each side of the equation. -15 + 15 + x = 13.747727085 + 15 Combine like terms: -15 + 15 = 0 0 + x = 13.747727085 + 15 x = 13.747727085 + 15 Combine like terms: 13.747727085 + 15 = 28.747727085 x = 28.747727085 Simplifying x = 28.747727085Subproblem 2
x + -15 = -13.747727085 Simplifying x + -15 = -13.747727085 Reorder the terms: -15 + x = -13.747727085 Solving -15 + x = -13.747727085 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '15' to each side of the equation. -15 + 15 + x = -13.747727085 + 15 Combine like terms: -15 + 15 = 0 0 + x = -13.747727085 + 15 x = -13.747727085 + 15 Combine like terms: -13.747727085 + 15 = 1.252272915 x = 1.252272915 Simplifying x = 1.252272915Solution
