Simplifying 7x(2x + 5) + 3 = 0 Reorder the terms: 7x(5 + 2x) + 3 = 0 (5 * 7x + 2x * 7x) + 3 = 0 (35x + 14x2) + 3 = 0 Reorder the terms: 3 + 35x + 14x2 = 0 Solving 3 + 35x + 14x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 14 the coefficient of the squared term: Divide each side by '14'. 0.2142857143 + 2.5x + x2 = 0 Move the constant term to the right: Add '-0.2142857143' to each side of the equation. 0.2142857143 + 2.5x + -0.2142857143 + x2 = 0 + -0.2142857143 Reorder the terms: 0.2142857143 + -0.2142857143 + 2.5x + x2 = 0 + -0.2142857143 Combine like terms: 0.2142857143 + -0.2142857143 = 0.0000000000 0.0000000000 + 2.5x + x2 = 0 + -0.2142857143 2.5x + x2 = 0 + -0.2142857143 Combine like terms: 0 + -0.2142857143 = -0.2142857143 2.5x + x2 = -0.2142857143 The x term is 2.5x. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x + 1.5625 + x2 = -0.2142857143 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = -0.2142857143 + 1.5625 Combine like terms: -0.2142857143 + 1.5625 = 1.3482142857 1.5625 + 2.5x + x2 = 1.3482142857 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 1.3482142857 Calculate the square root of the right side: 1.1611263 Break this problem into two subproblems by setting (x + 1.25) equal to 1.1611263 and -1.1611263.Subproblem 1
x + 1.25 = 1.1611263 Simplifying x + 1.25 = 1.1611263 Reorder the terms: 1.25 + x = 1.1611263 Solving 1.25 + x = 1.1611263 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = 1.1611263 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 1.1611263 + -1.25 x = 1.1611263 + -1.25 Combine like terms: 1.1611263 + -1.25 = -0.0888737 x = -0.0888737 Simplifying x = -0.0888737Subproblem 2
x + 1.25 = -1.1611263 Simplifying x + 1.25 = -1.1611263 Reorder the terms: 1.25 + x = -1.1611263 Solving 1.25 + x = -1.1611263 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = -1.1611263 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -1.1611263 + -1.25 x = -1.1611263 + -1.25 Combine like terms: -1.1611263 + -1.25 = -2.4111263 x = -2.4111263 Simplifying x = -2.4111263Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.0888737, -2.4111263}
