Simplifying 4x2 + 20x + -7 = 0 Reorder the terms: -7 + 20x + 4x2 = 0 Solving -7 + 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'. -1.75 + 5x + x2 = 0 Move the constant term to the right: Add '1.75' to each side of the equation. -1.75 + 5x + 1.75 + x2 = 0 + 1.75 Reorder the terms: -1.75 + 1.75 + 5x + x2 = 0 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + 5x + x2 = 0 + 1.75 5x + x2 = 0 + 1.75 Combine like terms: 0 + 1.75 = 1.75 5x + x2 = 1.75 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 = 1.75 + 6.25 Reorder the terms: 6.25 + 5x + x2 = 1.75 + 6.25 Combine like terms: 1.75 + 6.25 = 8 6.25 + 5x + x2 = 8 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 8 Calculate the square root of the right side: 2.828427125 Break this problem into two subproblems by setting (x + 2.5) equal to 2.828427125 and -2.828427125.Subproblem 1
x + 2.5 = 2.828427125 Simplifying x + 2.5 = 2.828427125 Reorder the terms: 2.5 + x = 2.828427125 Solving 2.5 + x = 2.828427125 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 = 2.828427125 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 2.828427125 + -2.5 x = 2.828427125 + -2.5 Combine like terms: 2.828427125 + -2.5 = 0.328427125 x = 0.328427125 Simplifying x = 0.328427125Subproblem 2
x + 2.5 = -2.828427125 Simplifying x + 2.5 = -2.828427125 Reorder the terms: 2.5 + x = -2.828427125 Solving 2.5 + x = -2.828427125 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 = -2.828427125 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -2.828427125 + -2.5 x = -2.828427125 + -2.5 Combine like terms: -2.828427125 + -2.5 = -5.328427125 x = -5.328427125 Simplifying x = -5.328427125Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.328427125, -5.328427125}
