Simplifying 0.08x2 + 1.6x + -16 = 0 Reorder the terms: -16 + 1.6x + 0.08x2 = 0 Solving -16 + 1.6x + 0.08x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.08 the coefficient of the squared term: Divide each side by '0.08'. -200 + 20x + x2 = 0 Move the constant term to the right: Add '200' to each side of the equation. -200 + 20x + 200 + x2 = 0 + 200 Reorder the terms: -200 + 200 + 20x + x2 = 0 + 200 Combine like terms: -200 + 200 = 0 0 + 20x + x2 = 0 + 200 20x + x2 = 0 + 200 Combine like terms: 0 + 200 = 200 20x + x2 = 200 The x term is 20x. Take half its coefficient (10). Square it (100) and add it to both sides. Add '100' to each side of the equation. 20x + 100 + x2 = 200 + 100 Reorder the terms: 100 + 20x + x2 = 200 + 100 Combine like terms: 200 + 100 = 300 100 + 20x + x2 = 300 Factor a perfect square on the left side: (x + 10)(x + 10) = 300 Calculate the square root of the right side: 17.320508076 Break this problem into two subproblems by setting (x + 10) equal to 17.320508076 and -17.320508076.Subproblem 1
x + 10 = 17.320508076 Simplifying x + 10 = 17.320508076 Reorder the terms: 10 + x = 17.320508076 Solving 10 + x = 17.320508076 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = 17.320508076 + -10 Combine like terms: 10 + -10 = 0 0 + x = 17.320508076 + -10 x = 17.320508076 + -10 Combine like terms: 17.320508076 + -10 = 7.320508076 x = 7.320508076 Simplifying x = 7.320508076Subproblem 2
x + 10 = -17.320508076 Simplifying x + 10 = -17.320508076 Reorder the terms: 10 + x = -17.320508076 Solving 10 + x = -17.320508076 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = -17.320508076 + -10 Combine like terms: 10 + -10 = 0 0 + x = -17.320508076 + -10 x = -17.320508076 + -10 Combine like terms: -17.320508076 + -10 = -27.320508076 x = -27.320508076 Simplifying x = -27.320508076Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.320508076, -27.320508076}
