Simplifying x = -10x2 + 6x + 7 Reorder the terms: x = 7 + 6x + -10x2 Solving x = 7 + 6x + -10x2 Solving for variable 'x'. Reorder the terms: -7 + x + -6x + 10x2 = 7 + 6x + -10x2 + -7 + -6x + 10x2 Combine like terms: x + -6x = -5x -7 + -5x + 10x2 = 7 + 6x + -10x2 + -7 + -6x + 10x2 Reorder the terms: -7 + -5x + 10x2 = 7 + -7 + 6x + -6x + -10x2 + 10x2 Combine like terms: 7 + -7 = 0 -7 + -5x + 10x2 = 0 + 6x + -6x + -10x2 + 10x2 -7 + -5x + 10x2 = 6x + -6x + -10x2 + 10x2 Combine like terms: 6x + -6x = 0 -7 + -5x + 10x2 = 0 + -10x2 + 10x2 -7 + -5x + 10x2 = -10x2 + 10x2 Combine like terms: -10x2 + 10x2 = 0 -7 + -5x + 10x2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -0.7 + -0.5x + x2 = 0 Move the constant term to the right: Add '0.7' to each side of the equation. -0.7 + -0.5x + 0.7 + x2 = 0 + 0.7 Reorder the terms: -0.7 + 0.7 + -0.5x + x2 = 0 + 0.7 Combine like terms: -0.7 + 0.7 = 0.0 0.0 + -0.5x + x2 = 0 + 0.7 -0.5x + x2 = 0 + 0.7 Combine like terms: 0 + 0.7 = 0.7 -0.5x + x2 = 0.7 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = 0.7 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 0.7 + 0.0625 Combine like terms: 0.7 + 0.0625 = 0.7625 0.0625 + -0.5x + x2 = 0.7625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 0.7625 Calculate the square root of the right side: 0.87321246 Break this problem into two subproblems by setting (x + -0.25) equal to 0.87321246 and -0.87321246.Subproblem 1
x + -0.25 = 0.87321246 Simplifying x + -0.25 = 0.87321246 Reorder the terms: -0.25 + x = 0.87321246 Solving -0.25 + x = 0.87321246 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 0.87321246 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 0.87321246 + 0.25 x = 0.87321246 + 0.25 Combine like terms: 0.87321246 + 0.25 = 1.12321246 x = 1.12321246 Simplifying x = 1.12321246Subproblem 2
x + -0.25 = -0.87321246 Simplifying x + -0.25 = -0.87321246 Reorder the terms: -0.25 + x = -0.87321246 Solving -0.25 + x = -0.87321246 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -0.87321246 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -0.87321246 + 0.25 x = -0.87321246 + 0.25 Combine like terms: -0.87321246 + 0.25 = -0.62321246 x = -0.62321246 Simplifying x = -0.62321246Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.12321246, -0.62321246}
