Simplifying 0 = -2.5x2 + 10x + 8 Reorder the terms: 0 = 8 + 10x + -2.5x2 Solving 0 = 8 + 10x + -2.5x2 Solving for variable 'x'. Combine like terms: 0 + -8 = -8 -8 + -10x + 2.5x2 = 8 + 10x + -2.5x2 + -8 + -10x + 2.5x2 Reorder the terms: -8 + -10x + 2.5x2 = 8 + -8 + 10x + -10x + -2.5x2 + 2.5x2 Combine like terms: 8 + -8 = 0 -8 + -10x + 2.5x2 = 0 + 10x + -10x + -2.5x2 + 2.5x2 -8 + -10x + 2.5x2 = 10x + -10x + -2.5x2 + 2.5x2 Combine like terms: 10x + -10x = 0 -8 + -10x + 2.5x2 = 0 + -2.5x2 + 2.5x2 -8 + -10x + 2.5x2 = -2.5x2 + 2.5x2 Combine like terms: -2.5x2 + 2.5x2 = 0.0 -8 + -10x + 2.5x2 = 0.0 Begin completing the square. Divide all terms by 2.5 the coefficient of the squared term: Divide each side by '2.5'. -3.2 + -4x + x2 = 0 Move the constant term to the right: Add '3.2' to each side of the equation. -3.2 + -4x + 3.2 + x2 = 0 + 3.2 Reorder the terms: -3.2 + 3.2 + -4x + x2 = 0 + 3.2 Combine like terms: -3.2 + 3.2 = 0.0 0.0 + -4x + x2 = 0 + 3.2 -4x + x2 = 0 + 3.2 Combine like terms: 0 + 3.2 = 3.2 -4x + x2 = 3.2 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = 3.2 + 4 Reorder the terms: 4 + -4x + x2 = 3.2 + 4 Combine like terms: 3.2 + 4 = 7.2 4 + -4x + x2 = 7.2 Factor a perfect square on the left side: (x + -2)(x + -2) = 7.2 Calculate the square root of the right side: 2.683281573 Break this problem into two subproblems by setting (x + -2) equal to 2.683281573 and -2.683281573.Subproblem 1
x + -2 = 2.683281573 Simplifying x + -2 = 2.683281573 Reorder the terms: -2 + x = 2.683281573 Solving -2 + x = 2.683281573 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 2.683281573 + 2 Combine like terms: -2 + 2 = 0 0 + x = 2.683281573 + 2 x = 2.683281573 + 2 Combine like terms: 2.683281573 + 2 = 4.683281573 x = 4.683281573 Simplifying x = 4.683281573Subproblem 2
x + -2 = -2.683281573 Simplifying x + -2 = -2.683281573 Reorder the terms: -2 + x = -2.683281573 Solving -2 + x = -2.683281573 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = -2.683281573 + 2 Combine like terms: -2 + 2 = 0 0 + x = -2.683281573 + 2 x = -2.683281573 + 2 Combine like terms: -2.683281573 + 2 = -0.683281573 x = -0.683281573 Simplifying x = -0.683281573Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.683281573, -0.683281573}
