Simplifying 7x(2x + 18) = 27 Reorder the terms: 7x(18 + 2x) = 27 (18 * 7x + 2x * 7x) = 27 (126x + 14x2) = 27 Solving 126x + 14x2 = 27 Solving for variable 'x'. Reorder the terms: -27 + 126x + 14x2 = 27 + -27 Combine like terms: 27 + -27 = 0 -27 + 126x + 14x2 = 0 Begin completing the square. Divide all terms by 14 the coefficient of the squared term: Divide each side by '14'. -1.928571429 + 9x + x2 = 0 Move the constant term to the right: Add '1.928571429' to each side of the equation. -1.928571429 + 9x + 1.928571429 + x2 = 0 + 1.928571429 Reorder the terms: -1.928571429 + 1.928571429 + 9x + x2 = 0 + 1.928571429 Combine like terms: -1.928571429 + 1.928571429 = 0.000000000 0.000000000 + 9x + x2 = 0 + 1.928571429 9x + x2 = 0 + 1.928571429 Combine like terms: 0 + 1.928571429 = 1.928571429 9x + x2 = 1.928571429 The x term is 9x. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9x + 20.25 + x2 = 1.928571429 + 20.25 Reorder the terms: 20.25 + 9x + x2 = 1.928571429 + 20.25 Combine like terms: 1.928571429 + 20.25 = 22.178571429 20.25 + 9x + x2 = 22.178571429 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 22.178571429 Calculate the square root of the right side: 4.709413066 Break this problem into two subproblems by setting (x + 4.5) equal to 4.709413066 and -4.709413066.Subproblem 1
x + 4.5 = 4.709413066 Simplifying x + 4.5 = 4.709413066 Reorder the terms: 4.5 + x = 4.709413066 Solving 4.5 + x = 4.709413066 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = 4.709413066 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 4.709413066 + -4.5 x = 4.709413066 + -4.5 Combine like terms: 4.709413066 + -4.5 = 0.209413066 x = 0.209413066 Simplifying x = 0.209413066Subproblem 2
x + 4.5 = -4.709413066 Simplifying x + 4.5 = -4.709413066 Reorder the terms: 4.5 + x = -4.709413066 Solving 4.5 + x = -4.709413066 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = -4.709413066 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -4.709413066 + -4.5 x = -4.709413066 + -4.5 Combine like terms: -4.709413066 + -4.5 = -9.209413066 x = -9.209413066 Simplifying x = -9.209413066Solution
