Simplifying -5x2 + 10x + 8 = 0 Reorder the terms: 8 + 10x + -5x2 = 0 Solving 8 + 10x + -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'. -1.6 + -2x + x2 = 0 Move the constant term to the right: Add '1.6' to each side of the equation. -1.6 + -2x + 1.6 + x2 = 0 + 1.6 Reorder the terms: -1.6 + 1.6 + -2x + x2 = 0 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + -2x + x2 = 0 + 1.6 -2x + x2 = 0 + 1.6 Combine like terms: 0 + 1.6 = 1.6 -2x + x2 = 1.6 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 1.6 + 1 Reorder the terms: 1 + -2x + x2 = 1.6 + 1 Combine like terms: 1.6 + 1 = 2.6 1 + -2x + x2 = 2.6 Factor a perfect square on the left side: (x + -1)(x + -1) = 2.6 Calculate the square root of the right side: 1.61245155 Break this problem into two subproblems by setting (x + -1) equal to 1.61245155 and -1.61245155.Subproblem 1
x + -1 = 1.61245155 Simplifying x + -1 = 1.61245155 Reorder the terms: -1 + x = 1.61245155 Solving -1 + x = 1.61245155 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 1.61245155 + 1 Combine like terms: -1 + 1 = 0 0 + x = 1.61245155 + 1 x = 1.61245155 + 1 Combine like terms: 1.61245155 + 1 = 2.61245155 x = 2.61245155 Simplifying x = 2.61245155Subproblem 2
x + -1 = -1.61245155 Simplifying x + -1 = -1.61245155 Reorder the terms: -1 + x = -1.61245155 Solving -1 + x = -1.61245155 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -1.61245155 + 1 Combine like terms: -1 + 1 = 0 0 + x = -1.61245155 + 1 x = -1.61245155 + 1 Combine like terms: -1.61245155 + 1 = -0.61245155 x = -0.61245155 Simplifying x = -0.61245155Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.61245155, -0.61245155}
