Simplifying 5x2 + 8x + 4 = 125 Reorder the terms: 4 + 8x + 5x2 = 125 Solving 4 + 8x + 5x2 = 125 Solving for variable 'x'. Reorder the terms: 4 + -125 + 8x + 5x2 = 125 + -125 Combine like terms: 4 + -125 = -121 -121 + 8x + 5x2 = 125 + -125 Combine like terms: 125 + -125 = 0 -121 + 8x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -24.2 + 1.6x + x2 = 0 Move the constant term to the right: Add '24.2' to each side of the equation. -24.2 + 1.6x + 24.2 + x2 = 0 + 24.2 Reorder the terms: -24.2 + 24.2 + 1.6x + x2 = 0 + 24.2 Combine like terms: -24.2 + 24.2 = 0.0 0.0 + 1.6x + x2 = 0 + 24.2 1.6x + x2 = 0 + 24.2 Combine like terms: 0 + 24.2 = 24.2 1.6x + x2 = 24.2 The x term is 1.6x. Take half its coefficient (0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. 1.6x + 0.64 + x2 = 24.2 + 0.64 Reorder the terms: 0.64 + 1.6x + x2 = 24.2 + 0.64 Combine like terms: 24.2 + 0.64 = 24.84 0.64 + 1.6x + x2 = 24.84 Factor a perfect square on the left side: (x + 0.8)(x + 0.8) = 24.84 Calculate the square root of the right side: 4.983974318 Break this problem into two subproblems by setting (x + 0.8) equal to 4.983974318 and -4.983974318.Subproblem 1
x + 0.8 = 4.983974318 Simplifying x + 0.8 = 4.983974318 Reorder the terms: 0.8 + x = 4.983974318 Solving 0.8 + x = 4.983974318 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.8' to each side of the equation. 0.8 + -0.8 + x = 4.983974318 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + x = 4.983974318 + -0.8 x = 4.983974318 + -0.8 Combine like terms: 4.983974318 + -0.8 = 4.183974318 x = 4.183974318 Simplifying x = 4.183974318Subproblem 2
x + 0.8 = -4.983974318 Simplifying x + 0.8 = -4.983974318 Reorder the terms: 0.8 + x = -4.983974318 Solving 0.8 + x = -4.983974318 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.8' to each side of the equation. 0.8 + -0.8 + x = -4.983974318 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + x = -4.983974318 + -0.8 x = -4.983974318 + -0.8 Combine like terms: -4.983974318 + -0.8 = -5.783974318 x = -5.783974318 Simplifying x = -5.783974318Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.183974318, -5.783974318}
