Simplifying x2 + -7x = 2 Reorder the terms: -7x + x2 = 2 Solving -7x + x2 = 2 Solving for variable 'x'. Reorder the terms: -2 + -7x + x2 = 2 + -2 Combine like terms: 2 + -2 = 0 -2 + -7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '2' to each side of the equation. -2 + -7x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + -7x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -7x + x2 = 0 + 2 -7x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 -7x + x2 = 2 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 = 2 + 12.25 Reorder the terms: 12.25 + -7x + x2 = 2 + 12.25 Combine like terms: 2 + 12.25 = 14.25 12.25 + -7x + x2 = 14.25 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = 14.25 Calculate the square root of the right side: 3.774917218 Break this problem into two subproblems by setting (x + -3.5) equal to 3.774917218 and -3.774917218.Subproblem 1
x + -3.5 = 3.774917218 Simplifying x + -3.5 = 3.774917218 Reorder the terms: -3.5 + x = 3.774917218 Solving -3.5 + x = 3.774917218 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 = 3.774917218 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = 3.774917218 + 3.5 x = 3.774917218 + 3.5 Combine like terms: 3.774917218 + 3.5 = 7.274917218 x = 7.274917218 Simplifying x = 7.274917218Subproblem 2
x + -3.5 = -3.774917218 Simplifying x + -3.5 = -3.774917218 Reorder the terms: -3.5 + x = -3.774917218 Solving -3.5 + x = -3.774917218 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 = -3.774917218 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = -3.774917218 + 3.5 x = -3.774917218 + 3.5 Combine like terms: -3.774917218 + 3.5 = -0.274917218 x = -0.274917218 Simplifying x = -0.274917218Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.274917218, -0.274917218}
