Simplifying 5x2 + 8x + -30 = 0 Reorder the terms: -30 + 8x + 5x2 = 0 Solving -30 + 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'. -6 + 1.6x + x2 = 0 Move the constant term to the right: Add '6' to each side of the equation. -6 + 1.6x + 6 + x2 = 0 + 6 Reorder the terms: -6 + 6 + 1.6x + x2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + 1.6x + x2 = 0 + 6 1.6x + x2 = 0 + 6 Combine like terms: 0 + 6 = 6 1.6x + x2 = 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 = 6 + 0.64 Reorder the terms: 0.64 + 1.6x + x2 = 6 + 0.64 Combine like terms: 6 + 0.64 = 6.64 0.64 + 1.6x + x2 = 6.64 Factor a perfect square on the left side: (x + 0.8)(x + 0.8) = 6.64 Calculate the square root of the right side: 2.576819745 Break this problem into two subproblems by setting (x + 0.8) equal to 2.576819745 and -2.576819745.Subproblem 1
x + 0.8 = 2.576819745 Simplifying x + 0.8 = 2.576819745 Reorder the terms: 0.8 + x = 2.576819745 Solving 0.8 + x = 2.576819745 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 = 2.576819745 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + x = 2.576819745 + -0.8 x = 2.576819745 + -0.8 Combine like terms: 2.576819745 + -0.8 = 1.776819745 x = 1.776819745 Simplifying x = 1.776819745Subproblem 2
x + 0.8 = -2.576819745 Simplifying x + 0.8 = -2.576819745 Reorder the terms: 0.8 + x = -2.576819745 Solving 0.8 + x = -2.576819745 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 = -2.576819745 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + x = -2.576819745 + -0.8 x = -2.576819745 + -0.8 Combine like terms: -2.576819745 + -0.8 = -3.376819745 x = -3.376819745 Simplifying x = -3.376819745Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.776819745, -3.376819745}
