Simplifying 4x2 + 20x + -49 = 0 Reorder the terms: -49 + 20x + 4x2 = 0 Solving -49 + 20x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -12.25 + 5x + x2 = 0 Move the constant term to the right: Add '12.25' to each side of the equation. -12.25 + 5x + 12.25 + x2 = 0 + 12.25 Reorder the terms: -12.25 + 12.25 + 5x + x2 = 0 + 12.25 Combine like terms: -12.25 + 12.25 = 0.00 0.00 + 5x + x2 = 0 + 12.25 5x + x2 = 0 + 12.25 Combine like terms: 0 + 12.25 = 12.25 5x + x2 = 12.25 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 = 12.25 + 6.25 Reorder the terms: 6.25 + 5x + x2 = 12.25 + 6.25 Combine like terms: 12.25 + 6.25 = 18.5 6.25 + 5x + x2 = 18.5 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 18.5 Calculate the square root of the right side: 4.301162634 Break this problem into two subproblems by setting (x + 2.5) equal to 4.301162634 and -4.301162634.Subproblem 1
x + 2.5 = 4.301162634 Simplifying x + 2.5 = 4.301162634 Reorder the terms: 2.5 + x = 4.301162634 Solving 2.5 + x = 4.301162634 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 = 4.301162634 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 4.301162634 + -2.5 x = 4.301162634 + -2.5 Combine like terms: 4.301162634 + -2.5 = 1.801162634 x = 1.801162634 Simplifying x = 1.801162634Subproblem 2
x + 2.5 = -4.301162634 Simplifying x + 2.5 = -4.301162634 Reorder the terms: 2.5 + x = -4.301162634 Solving 2.5 + x = -4.301162634 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 = -4.301162634 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -4.301162634 + -2.5 x = -4.301162634 + -2.5 Combine like terms: -4.301162634 + -2.5 = -6.801162634 x = -6.801162634 Simplifying x = -6.801162634Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.801162634, -6.801162634}
