Simplifying x2 + 13x + 7 = 0 Reorder the terms: 7 + 13x + x2 = 0 Solving 7 + 13x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-7' to each side of the equation. 7 + 13x + -7 + x2 = 0 + -7 Reorder the terms: 7 + -7 + 13x + x2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 13x + x2 = 0 + -7 13x + x2 = 0 + -7 Combine like terms: 0 + -7 = -7 13x + x2 = -7 The x term is 13x. Take half its coefficient (6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. 13x + 42.25 + x2 = -7 + 42.25 Reorder the terms: 42.25 + 13x + x2 = -7 + 42.25 Combine like terms: -7 + 42.25 = 35.25 42.25 + 13x + x2 = 35.25 Factor a perfect square on the left side: (x + 6.5)(x + 6.5) = 35.25 Calculate the square root of the right side: 5.937171044 Break this problem into two subproblems by setting (x + 6.5) equal to 5.937171044 and -5.937171044.Subproblem 1
x + 6.5 = 5.937171044 Simplifying x + 6.5 = 5.937171044 Reorder the terms: 6.5 + x = 5.937171044 Solving 6.5 + x = 5.937171044 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = 5.937171044 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = 5.937171044 + -6.5 x = 5.937171044 + -6.5 Combine like terms: 5.937171044 + -6.5 = -0.562828956 x = -0.562828956 Simplifying x = -0.562828956Subproblem 2
x + 6.5 = -5.937171044 Simplifying x + 6.5 = -5.937171044 Reorder the terms: 6.5 + x = -5.937171044 Solving 6.5 + x = -5.937171044 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = -5.937171044 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = -5.937171044 + -6.5 x = -5.937171044 + -6.5 Combine like terms: -5.937171044 + -6.5 = -12.437171044 x = -12.437171044 Simplifying x = -12.437171044Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.562828956, -12.437171044}
