Simplifying 5x(x + 3) + 7x = -7 Reorder the terms: 5x(3 + x) + 7x = -7 (3 * 5x + x * 5x) + 7x = -7 (15x + 5x2) + 7x = -7 Reorder the terms: 15x + 7x + 5x2 = -7 Combine like terms: 15x + 7x = 22x 22x + 5x2 = -7 Solving 22x + 5x2 = -7 Solving for variable 'x'. Reorder the terms: 7 + 22x + 5x2 = -7 + 7 Combine like terms: -7 + 7 = 0 7 + 22x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 1.4 + 4.4x + x2 = 0 Move the constant term to the right: Add '-1.4' to each side of the equation. 1.4 + 4.4x + -1.4 + x2 = 0 + -1.4 Reorder the terms: 1.4 + -1.4 + 4.4x + x2 = 0 + -1.4 Combine like terms: 1.4 + -1.4 = 0.0 0.0 + 4.4x + x2 = 0 + -1.4 4.4x + x2 = 0 + -1.4 Combine like terms: 0 + -1.4 = -1.4 4.4x + x2 = -1.4 The x term is 4.4x. Take half its coefficient (2.2). Square it (4.84) and add it to both sides. Add '4.84' to each side of the equation. 4.4x + 4.84 + x2 = -1.4 + 4.84 Reorder the terms: 4.84 + 4.4x + x2 = -1.4 + 4.84 Combine like terms: -1.4 + 4.84 = 3.44 4.84 + 4.4x + x2 = 3.44 Factor a perfect square on the left side: (x + 2.2)(x + 2.2) = 3.44 Calculate the square root of the right side: 1.854723699 Break this problem into two subproblems by setting (x + 2.2) equal to 1.854723699 and -1.854723699.Subproblem 1
x + 2.2 = 1.854723699 Simplifying x + 2.2 = 1.854723699 Reorder the terms: 2.2 + x = 1.854723699 Solving 2.2 + x = 1.854723699 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.2' to each side of the equation. 2.2 + -2.2 + x = 1.854723699 + -2.2 Combine like terms: 2.2 + -2.2 = 0.0 0.0 + x = 1.854723699 + -2.2 x = 1.854723699 + -2.2 Combine like terms: 1.854723699 + -2.2 = -0.345276301 x = -0.345276301 Simplifying x = -0.345276301Subproblem 2
x + 2.2 = -1.854723699 Simplifying x + 2.2 = -1.854723699 Reorder the terms: 2.2 + x = -1.854723699 Solving 2.2 + x = -1.854723699 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.2' to each side of the equation. 2.2 + -2.2 + x = -1.854723699 + -2.2 Combine like terms: 2.2 + -2.2 = 0.0 0.0 + x = -1.854723699 + -2.2 x = -1.854723699 + -2.2 Combine like terms: -1.854723699 + -2.2 = -4.054723699 x = -4.054723699 Simplifying x = -4.054723699Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.345276301, -4.054723699}
