Simplifying x(x + 4) = 400 Reorder the terms: x(4 + x) = 400 (4 * x + x * x) = 400 (4x + x2) = 400 Solving 4x + x2 = 400 Solving for variable 'x'. Reorder the terms: -400 + 4x + x2 = 400 + -400 Combine like terms: 400 + -400 = 0 -400 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '400' to each side of the equation. -400 + 4x + 400 + x2 = 0 + 400 Reorder the terms: -400 + 400 + 4x + x2 = 0 + 400 Combine like terms: -400 + 400 = 0 0 + 4x + x2 = 0 + 400 4x + x2 = 0 + 400 Combine like terms: 0 + 400 = 400 4x + x2 = 400 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = 400 + 4 Reorder the terms: 4 + 4x + x2 = 400 + 4 Combine like terms: 400 + 4 = 404 4 + 4x + x2 = 404 Factor a perfect square on the left side: (x + 2)(x + 2) = 404 Calculate the square root of the right side: 20.099751242 Break this problem into two subproblems by setting (x + 2) equal to 20.099751242 and -20.099751242.Subproblem 1
x + 2 = 20.099751242 Simplifying x + 2 = 20.099751242 Reorder the terms: 2 + x = 20.099751242 Solving 2 + x = 20.099751242 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 20.099751242 + -2 Combine like terms: 2 + -2 = 0 0 + x = 20.099751242 + -2 x = 20.099751242 + -2 Combine like terms: 20.099751242 + -2 = 18.099751242 x = 18.099751242 Simplifying x = 18.099751242Subproblem 2
x + 2 = -20.099751242 Simplifying x + 2 = -20.099751242 Reorder the terms: 2 + x = -20.099751242 Solving 2 + x = -20.099751242 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -20.099751242 + -2 Combine like terms: 2 + -2 = 0 0 + x = -20.099751242 + -2 x = -20.099751242 + -2 Combine like terms: -20.099751242 + -2 = -22.099751242 x = -22.099751242 Simplifying x = -22.099751242Solution
The solution to the problem is based on the solutions from the subproblems. x = {18.099751242, -22.099751242}
