Simplifying (x + 5)(x + 4) = 36 Reorder the terms: (5 + x)(x + 4) = 36 Reorder the terms: (5 + x)(4 + x) = 36 Multiply (5 + x) * (4 + x) (5(4 + x) + x(4 + x)) = 36 ((4 * 5 + x * 5) + x(4 + x)) = 36 ((20 + 5x) + x(4 + x)) = 36 (20 + 5x + (4 * x + x * x)) = 36 (20 + 5x + (4x + x2)) = 36 Combine like terms: 5x + 4x = 9x (20 + 9x + x2) = 36 Solving 20 + 9x + x2 = 36 Solving for variable 'x'. Reorder the terms: 20 + -36 + 9x + x2 = 36 + -36 Combine like terms: 20 + -36 = -16 -16 + 9x + x2 = 36 + -36 Combine like terms: 36 + -36 = 0 -16 + 9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '16' to each side of the equation. -16 + 9x + 16 + x2 = 0 + 16 Reorder the terms: -16 + 16 + 9x + x2 = 0 + 16 Combine like terms: -16 + 16 = 0 0 + 9x + x2 = 0 + 16 9x + x2 = 0 + 16 Combine like terms: 0 + 16 = 16 9x + x2 = 16 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 = 16 + 20.25 Reorder the terms: 20.25 + 9x + x2 = 16 + 20.25 Combine like terms: 16 + 20.25 = 36.25 20.25 + 9x + x2 = 36.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 36.25 Calculate the square root of the right side: 6.020797289 Break this problem into two subproblems by setting (x + 4.5) equal to 6.020797289 and -6.020797289.Subproblem 1
x + 4.5 = 6.020797289 Simplifying x + 4.5 = 6.020797289 Reorder the terms: 4.5 + x = 6.020797289 Solving 4.5 + x = 6.020797289 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 = 6.020797289 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 6.020797289 + -4.5 x = 6.020797289 + -4.5 Combine like terms: 6.020797289 + -4.5 = 1.520797289 x = 1.520797289 Simplifying x = 1.520797289Subproblem 2
x + 4.5 = -6.020797289 Simplifying x + 4.5 = -6.020797289 Reorder the terms: 4.5 + x = -6.020797289 Solving 4.5 + x = -6.020797289 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 = -6.020797289 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -6.020797289 + -4.5 x = -6.020797289 + -4.5 Combine like terms: -6.020797289 + -4.5 = -10.520797289 x = -10.520797289 Simplifying x = -10.520797289Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.520797289, -10.520797289}
