Simplifying -10x2 + 10x + 7 = 0 Reorder the terms: 7 + 10x + -10x2 = 0 Solving 7 + 10x + -10x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -10 the coefficient of the squared term: Divide each side by '-10'. -0.7 + -1x + x2 = 0 Move the constant term to the right: Add '0.7' to each side of the equation. -0.7 + -1x + 0.7 + x2 = 0 + 0.7 Reorder the terms: -0.7 + 0.7 + -1x + x2 = 0 + 0.7 Combine like terms: -0.7 + 0.7 = 0.0 0.0 + -1x + x2 = 0 + 0.7 -1x + x2 = 0 + 0.7 Combine like terms: 0 + 0.7 = 0.7 -1x + x2 = 0.7 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = 0.7 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 0.7 + 0.25 Combine like terms: 0.7 + 0.25 = 0.95 0.25 + -1x + x2 = 0.95 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 0.95 Calculate the square root of the right side: 0.974679434 Break this problem into two subproblems by setting (x + -0.5) equal to 0.974679434 and -0.974679434.Subproblem 1
x + -0.5 = 0.974679434 Simplifying x + -0.5 = 0.974679434 Reorder the terms: -0.5 + x = 0.974679434 Solving -0.5 + x = 0.974679434 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 0.974679434 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 0.974679434 + 0.5 x = 0.974679434 + 0.5 Combine like terms: 0.974679434 + 0.5 = 1.474679434 x = 1.474679434 Simplifying x = 1.474679434Subproblem 2
x + -0.5 = -0.974679434 Simplifying x + -0.5 = -0.974679434 Reorder the terms: -0.5 + x = -0.974679434 Solving -0.5 + x = -0.974679434 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -0.974679434 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -0.974679434 + 0.5 x = -0.974679434 + 0.5 Combine like terms: -0.974679434 + 0.5 = -0.474679434 x = -0.474679434 Simplifying x = -0.474679434Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.474679434, -0.474679434}
