Simplifying x(x + 1(x + 2(x + 3(x + 4)))) = 10 Reorder the terms: x(x + 1(x + 2(x + 3(4 + x)))) = 10 x(x + 1(x + 2(x + (4 * 3 + x * 3)))) = 10 x(x + 1(x + 2(x + (12 + 3x)))) = 10 Reorder the terms: x(x + 1(x + 2(12 + x + 3x))) = 10 Combine like terms: x + 3x = 4x x(x + 1(x + 2(12 + 4x))) = 10 x(x + 1(x + (12 * 2 + 4x * 2))) = 10 x(x + 1(x + (24 + 8x))) = 10 Reorder the terms: x(x + 1(24 + x + 8x)) = 10 Combine like terms: x + 8x = 9x x(x + 1(24 + 9x)) = 10 x(x + (24 * 1 + 9x * 1)) = 10 x(x + (24 + 9x)) = 10 Reorder the terms: x(24 + x + 9x) = 10 Combine like terms: x + 9x = 10x x(24 + 10x) = 10 (24 * x + 10x * x) = 10 (24x + 10x2) = 10 Solving 24x + 10x2 = 10 Solving for variable 'x'. Reorder the terms: -10 + 24x + 10x2 = 10 + -10 Combine like terms: 10 + -10 = 0 -10 + 24x + 10x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-5 + 12x + 5x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-5 + 12x + 5x2)' equal to zero and attempt to solve: Simplifying -5 + 12x + 5x2 = 0 Solving -5 + 12x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1 + 2.4x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + 2.4x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + 2.4x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 2.4x + x2 = 0 + 1 2.4x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 2.4x + x2 = 1 The x term is 2.4x. Take half its coefficient (1.2). Square it (1.44) and add it to both sides. Add '1.44' to each side of the equation. 2.4x + 1.44 + x2 = 1 + 1.44 Reorder the terms: 1.44 + 2.4x + x2 = 1 + 1.44 Combine like terms: 1 + 1.44 = 2.44 1.44 + 2.4x + x2 = 2.44 Factor a perfect square on the left side: (x + 1.2)(x + 1.2) = 2.44 Calculate the square root of the right side: 1.562049935 Break this problem into two subproblems by setting (x + 1.2) equal to 1.562049935 and -1.562049935.Subproblem 1
x + 1.2 = 1.562049935 Simplifying x + 1.2 = 1.562049935 Reorder the terms: 1.2 + x = 1.562049935 Solving 1.2 + x = 1.562049935 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + x = 1.562049935 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + x = 1.562049935 + -1.2 x = 1.562049935 + -1.2 Combine like terms: 1.562049935 + -1.2 = 0.362049935 x = 0.362049935 Simplifying x = 0.362049935Subproblem 2
x + 1.2 = -1.562049935 Simplifying x + 1.2 = -1.562049935 Reorder the terms: 1.2 + x = -1.562049935 Solving 1.2 + x = -1.562049935 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + x = -1.562049935 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + x = -1.562049935 + -1.2 x = -1.562049935 + -1.2 Combine like terms: -1.562049935 + -1.2 = -2.762049935 x = -2.762049935 Simplifying x = -2.762049935Solution
