Simplifying x(7 + -1x) = 8 (7 * x + -1x * x) = 8 (7x + -1x2) = 8 Solving 7x + -1x2 = 8 Solving for variable 'x'. Reorder the terms: -8 + 7x + -1x2 = 8 + -8 Combine like terms: 8 + -8 = 0 -8 + 7x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 8 + -7x + x2 = 0 Move the constant term to the right: Add '-8' to each side of the equation. 8 + -7x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + -7x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -7x + x2 = 0 + -8 -7x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 -7x + x2 = -8 The x term is -7x. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7x + 12.25 + x2 = -8 + 12.25 Reorder the terms: 12.25 + -7x + x2 = -8 + 12.25 Combine like terms: -8 + 12.25 = 4.25 12.25 + -7x + x2 = 4.25 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = 4.25 Calculate the square root of the right side: 2.061552813 Break this problem into two subproblems by setting (x + -3.5) equal to 2.061552813 and -2.061552813.Subproblem 1
x + -3.5 = 2.061552813 Simplifying x + -3.5 = 2.061552813 Reorder the terms: -3.5 + x = 2.061552813 Solving -3.5 + x = 2.061552813 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + x = 2.061552813 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = 2.061552813 + 3.5 x = 2.061552813 + 3.5 Combine like terms: 2.061552813 + 3.5 = 5.561552813 x = 5.561552813 Simplifying x = 5.561552813Subproblem 2
x + -3.5 = -2.061552813 Simplifying x + -3.5 = -2.061552813 Reorder the terms: -3.5 + x = -2.061552813 Solving -3.5 + x = -2.061552813 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + x = -2.061552813 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = -2.061552813 + 3.5 x = -2.061552813 + 3.5 Combine like terms: -2.061552813 + 3.5 = 1.438447187 x = 1.438447187 Simplifying x = 1.438447187Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.561552813, 1.438447187}
