Simplifying 5x2 + 8x + -28 = 0 Reorder the terms: -28 + 8x + 5x2 = 0 Solving -28 + 8x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -5.6 + 1.6x + x2 = 0 Move the constant term to the right: Add '5.6' to each side of the equation. -5.6 + 1.6x + 5.6 + x2 = 0 + 5.6 Reorder the terms: -5.6 + 5.6 + 1.6x + x2 = 0 + 5.6 Combine like terms: -5.6 + 5.6 = 0.0 0.0 + 1.6x + x2 = 0 + 5.6 1.6x + x2 = 0 + 5.6 Combine like terms: 0 + 5.6 = 5.6 1.6x + x2 = 5.6 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 = 5.6 + 0.64 Reorder the terms: 0.64 + 1.6x + x2 = 5.6 + 0.64 Combine like terms: 5.6 + 0.64 = 6.24 0.64 + 1.6x + x2 = 6.24 Factor a perfect square on the left side: (x + 0.8)(x + 0.8) = 6.24 Calculate the square root of the right side: 2.497999199 Break this problem into two subproblems by setting (x + 0.8) equal to 2.497999199 and -2.497999199.Subproblem 1
x + 0.8 = 2.497999199 Simplifying x + 0.8 = 2.497999199 Reorder the terms: 0.8 + x = 2.497999199 Solving 0.8 + x = 2.497999199 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 = 2.497999199 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + x = 2.497999199 + -0.8 x = 2.497999199 + -0.8 Combine like terms: 2.497999199 + -0.8 = 1.697999199 x = 1.697999199 Simplifying x = 1.697999199Subproblem 2
x + 0.8 = -2.497999199 Simplifying x + 0.8 = -2.497999199 Reorder the terms: 0.8 + x = -2.497999199 Solving 0.8 + x = -2.497999199 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 = -2.497999199 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + x = -2.497999199 + -0.8 x = -2.497999199 + -0.8 Combine like terms: -2.497999199 + -0.8 = -3.297999199 x = -3.297999199 Simplifying x = -3.297999199Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.697999199, -3.297999199}
