Simplifying x * 5x + 4x = 45 Reorder the terms for easier multiplication: 5x * x + 4x = 45 Multiply x * x 5x2 + 4x = 45 Reorder the terms: 4x + 5x2 = 45 Solving 4x + 5x2 = 45 Solving for variable 'x'. Reorder the terms: -45 + 4x + 5x2 = 45 + -45 Combine like terms: 45 + -45 = 0 -45 + 4x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -9 + 0.8x + x2 = 0 Move the constant term to the right: Add '9' to each side of the equation. -9 + 0.8x + 9 + x2 = 0 + 9 Reorder the terms: -9 + 9 + 0.8x + x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + 0.8x + x2 = 0 + 9 0.8x + x2 = 0 + 9 Combine like terms: 0 + 9 = 9 0.8x + x2 = 9 The x term is 0.8x. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8x + 0.16 + x2 = 9 + 0.16 Reorder the terms: 0.16 + 0.8x + x2 = 9 + 0.16 Combine like terms: 9 + 0.16 = 9.16 0.16 + 0.8x + x2 = 9.16 Factor a perfect square on the left side: (x + 0.4)(x + 0.4) = 9.16 Calculate the square root of the right side: 3.02654919 Break this problem into two subproblems by setting (x + 0.4) equal to 3.02654919 and -3.02654919.Subproblem 1
x + 0.4 = 3.02654919 Simplifying x + 0.4 = 3.02654919 Reorder the terms: 0.4 + x = 3.02654919 Solving 0.4 + x = 3.02654919 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = 3.02654919 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = 3.02654919 + -0.4 x = 3.02654919 + -0.4 Combine like terms: 3.02654919 + -0.4 = 2.62654919 x = 2.62654919 Simplifying x = 2.62654919Subproblem 2
x + 0.4 = -3.02654919 Simplifying x + 0.4 = -3.02654919 Reorder the terms: 0.4 + x = -3.02654919 Solving 0.4 + x = -3.02654919 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = -3.02654919 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = -3.02654919 + -0.4 x = -3.02654919 + -0.4 Combine like terms: -3.02654919 + -0.4 = -3.42654919 x = -3.42654919 Simplifying x = -3.42654919Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.62654919, -3.42654919}
