Simplifying x(x + 5) = -3 Reorder the terms: x(5 + x) = -3 (5 * x + x * x) = -3 (5x + x2) = -3 Solving 5x + x2 = -3 Solving for variable 'x'. Reorder the terms: 3 + 5x + x2 = -3 + 3 Combine like terms: -3 + 3 = 0 3 + 5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-3' to each side of the equation. 3 + 5x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + 5x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 5x + x2 = 0 + -3 5x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 5x + x2 = -3 The x term is 5x. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5x + 6.25 + x2 = -3 + 6.25 Reorder the terms: 6.25 + 5x + x2 = -3 + 6.25 Combine like terms: -3 + 6.25 = 3.25 6.25 + 5x + x2 = 3.25 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 3.25 Calculate the square root of the right side: 1.802775638 Break this problem into two subproblems by setting (x + 2.5) equal to 1.802775638 and -1.802775638.Subproblem 1
x + 2.5 = 1.802775638 Simplifying x + 2.5 = 1.802775638 Reorder the terms: 2.5 + x = 1.802775638 Solving 2.5 + x = 1.802775638 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = 1.802775638 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 1.802775638 + -2.5 x = 1.802775638 + -2.5 Combine like terms: 1.802775638 + -2.5 = -0.697224362 x = -0.697224362 Simplifying x = -0.697224362Subproblem 2
x + 2.5 = -1.802775638 Simplifying x + 2.5 = -1.802775638 Reorder the terms: 2.5 + x = -1.802775638 Solving 2.5 + x = -1.802775638 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = -1.802775638 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -1.802775638 + -2.5 x = -1.802775638 + -2.5 Combine like terms: -1.802775638 + -2.5 = -4.302775638 x = -4.302775638 Simplifying x = -4.302775638Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.697224362, -4.302775638}
