Simplifying 9x = 8 + -5x2 Solving 9x = 8 + -5x2 Solving for variable 'x'. Reorder the terms: -8 + 9x + 5x2 = 8 + -5x2 + -8 + 5x2 Reorder the terms: -8 + 9x + 5x2 = 8 + -8 + -5x2 + 5x2 Combine like terms: 8 + -8 = 0 -8 + 9x + 5x2 = 0 + -5x2 + 5x2 -8 + 9x + 5x2 = -5x2 + 5x2 Combine like terms: -5x2 + 5x2 = 0 -8 + 9x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1.6 + 1.8x + x2 = 0 Move the constant term to the right: Add '1.6' to each side of the equation. -1.6 + 1.8x + 1.6 + x2 = 0 + 1.6 Reorder the terms: -1.6 + 1.6 + 1.8x + x2 = 0 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + 1.8x + x2 = 0 + 1.6 1.8x + x2 = 0 + 1.6 Combine like terms: 0 + 1.6 = 1.6 1.8x + x2 = 1.6 The x term is 1.8x. Take half its coefficient (0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. 1.8x + 0.81 + x2 = 1.6 + 0.81 Reorder the terms: 0.81 + 1.8x + x2 = 1.6 + 0.81 Combine like terms: 1.6 + 0.81 = 2.41 0.81 + 1.8x + x2 = 2.41 Factor a perfect square on the left side: (x + 0.9)(x + 0.9) = 2.41 Calculate the square root of the right side: 1.55241747 Break this problem into two subproblems by setting (x + 0.9) equal to 1.55241747 and -1.55241747.Subproblem 1
x + 0.9 = 1.55241747 Simplifying x + 0.9 = 1.55241747 Reorder the terms: 0.9 + x = 1.55241747 Solving 0.9 + x = 1.55241747 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + x = 1.55241747 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + x = 1.55241747 + -0.9 x = 1.55241747 + -0.9 Combine like terms: 1.55241747 + -0.9 = 0.65241747 x = 0.65241747 Simplifying x = 0.65241747Subproblem 2
x + 0.9 = -1.55241747 Simplifying x + 0.9 = -1.55241747 Reorder the terms: 0.9 + x = -1.55241747 Solving 0.9 + x = -1.55241747 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + x = -1.55241747 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + x = -1.55241747 + -0.9 x = -1.55241747 + -0.9 Combine like terms: -1.55241747 + -0.9 = -2.45241747 x = -2.45241747 Simplifying x = -2.45241747Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.65241747, -2.45241747}
