Simplifying 2x + 7(10x + 200) = x(x + 5) Reorder the terms: 2x + 7(200 + 10x) = x(x + 5) 2x + (200 * 7 + 10x * 7) = x(x + 5) 2x + (1400 + 70x) = x(x + 5) Reorder the terms: 1400 + 2x + 70x = x(x + 5) Combine like terms: 2x + 70x = 72x 1400 + 72x = x(x + 5) Reorder the terms: 1400 + 72x = x(5 + x) 1400 + 72x = (5 * x + x * x) 1400 + 72x = (5x + x2) Solving 1400 + 72x = 5x + x2 Solving for variable 'x'. Combine like terms: 72x + -5x = 67x 1400 + 67x + -1x2 = 5x + x2 + -5x + -1x2 Reorder the terms: 1400 + 67x + -1x2 = 5x + -5x + x2 + -1x2 Combine like terms: 5x + -5x = 0 1400 + 67x + -1x2 = 0 + x2 + -1x2 1400 + 67x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 1400 + 67x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -1400 + -67x + x2 = 0 Move the constant term to the right: Add '1400' to each side of the equation. -1400 + -67x + 1400 + x2 = 0 + 1400 Reorder the terms: -1400 + 1400 + -67x + x2 = 0 + 1400 Combine like terms: -1400 + 1400 = 0 0 + -67x + x2 = 0 + 1400 -67x + x2 = 0 + 1400 Combine like terms: 0 + 1400 = 1400 -67x + x2 = 1400 The x term is -67x. Take half its coefficient (-33.5). Square it (1122.25) and add it to both sides. Add '1122.25' to each side of the equation. -67x + 1122.25 + x2 = 1400 + 1122.25 Reorder the terms: 1122.25 + -67x + x2 = 1400 + 1122.25 Combine like terms: 1400 + 1122.25 = 2522.25 1122.25 + -67x + x2 = 2522.25 Factor a perfect square on the left side: (x + -33.5)(x + -33.5) = 2522.25 Calculate the square root of the right side: 50.222007128 Break this problem into two subproblems by setting (x + -33.5) equal to 50.222007128 and -50.222007128.Subproblem 1
x + -33.5 = 50.222007128 Simplifying x + -33.5 = 50.222007128 Reorder the terms: -33.5 + x = 50.222007128 Solving -33.5 + x = 50.222007128 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '33.5' to each side of the equation. -33.5 + 33.5 + x = 50.222007128 + 33.5 Combine like terms: -33.5 + 33.5 = 0.0 0.0 + x = 50.222007128 + 33.5 x = 50.222007128 + 33.5 Combine like terms: 50.222007128 + 33.5 = 83.722007128 x = 83.722007128 Simplifying x = 83.722007128Subproblem 2
x + -33.5 = -50.222007128 Simplifying x + -33.5 = -50.222007128 Reorder the terms: -33.5 + x = -50.222007128 Solving -33.5 + x = -50.222007128 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '33.5' to each side of the equation. -33.5 + 33.5 + x = -50.222007128 + 33.5 Combine like terms: -33.5 + 33.5 = 0.0 0.0 + x = -50.222007128 + 33.5 x = -50.222007128 + 33.5 Combine like terms: -50.222007128 + 33.5 = -16.722007128 x = -16.722007128 Simplifying x = -16.722007128Solution
