Simplifying (4x2 + -4x + 23) + (4x2 + 8x + -42) = 0 Reorder the terms: (23 + -4x + 4x2) + (4x2 + 8x + -42) = 0 Remove parenthesis around (23 + -4x + 4x2) 23 + -4x + 4x2 + (4x2 + 8x + -42) = 0 Reorder the terms: 23 + -4x + 4x2 + (-42 + 8x + 4x2) = 0 Remove parenthesis around (-42 + 8x + 4x2) 23 + -4x + 4x2 + -42 + 8x + 4x2 = 0 Reorder the terms: 23 + -42 + -4x + 8x + 4x2 + 4x2 = 0 Combine like terms: 23 + -42 = -19 -19 + -4x + 8x + 4x2 + 4x2 = 0 Combine like terms: -4x + 8x = 4x -19 + 4x + 4x2 + 4x2 = 0 Combine like terms: 4x2 + 4x2 = 8x2 -19 + 4x + 8x2 = 0 Solving -19 + 4x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -2.375 + 0.5x + x2 = 0 Move the constant term to the right: Add '2.375' to each side of the equation. -2.375 + 0.5x + 2.375 + x2 = 0 + 2.375 Reorder the terms: -2.375 + 2.375 + 0.5x + x2 = 0 + 2.375 Combine like terms: -2.375 + 2.375 = 0.000 0.000 + 0.5x + x2 = 0 + 2.375 0.5x + x2 = 0 + 2.375 Combine like terms: 0 + 2.375 = 2.375 0.5x + x2 = 2.375 The x term is 0.5x. Take half its coefficient (0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. 0.5x + 0.0625 + x2 = 2.375 + 0.0625 Reorder the terms: 0.0625 + 0.5x + x2 = 2.375 + 0.0625 Combine like terms: 2.375 + 0.0625 = 2.4375 0.0625 + 0.5x + x2 = 2.4375 Factor a perfect square on the left side: (x + 0.25)(x + 0.25) = 2.4375 Calculate the square root of the right side: 1.5612495 Break this problem into two subproblems by setting (x + 0.25) equal to 1.5612495 and -1.5612495.Subproblem 1
x + 0.25 = 1.5612495 Simplifying x + 0.25 = 1.5612495 Reorder the terms: 0.25 + x = 1.5612495 Solving 0.25 + x = 1.5612495 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + x = 1.5612495 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + x = 1.5612495 + -0.25 x = 1.5612495 + -0.25 Combine like terms: 1.5612495 + -0.25 = 1.3112495 x = 1.3112495 Simplifying x = 1.3112495Subproblem 2
x + 0.25 = -1.5612495 Simplifying x + 0.25 = -1.5612495 Reorder the terms: 0.25 + x = -1.5612495 Solving 0.25 + x = -1.5612495 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + x = -1.5612495 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + x = -1.5612495 + -0.25 x = -1.5612495 + -0.25 Combine like terms: -1.5612495 + -0.25 = -1.8112495 x = -1.8112495 Simplifying x = -1.8112495Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.3112495, -1.8112495}
