Simplifying x2 + 6x + 9 = 13 Reorder the terms: 9 + 6x + x2 = 13 Solving 9 + 6x + x2 = 13 Solving for variable 'x'. Reorder the terms: 9 + -13 + 6x + x2 = 13 + -13 Combine like terms: 9 + -13 = -4 -4 + 6x + x2 = 13 + -13 Combine like terms: 13 + -13 = 0 -4 + 6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '4' to each side of the equation. -4 + 6x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + 6x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 6x + x2 = 0 + 4 6x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 6x + x2 = 4 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = 4 + 9 Reorder the terms: 9 + 6x + x2 = 4 + 9 Combine like terms: 4 + 9 = 13 9 + 6x + x2 = 13 Factor a perfect square on the left side: (x + 3)(x + 3) = 13 Calculate the square root of the right side: 3.605551275 Break this problem into two subproblems by setting (x + 3) equal to 3.605551275 and -3.605551275.Subproblem 1
x + 3 = 3.605551275 Simplifying x + 3 = 3.605551275 Reorder the terms: 3 + x = 3.605551275 Solving 3 + x = 3.605551275 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 3.605551275 + -3 Combine like terms: 3 + -3 = 0 0 + x = 3.605551275 + -3 x = 3.605551275 + -3 Combine like terms: 3.605551275 + -3 = 0.605551275 x = 0.605551275 Simplifying x = 0.605551275Subproblem 2
x + 3 = -3.605551275 Simplifying x + 3 = -3.605551275 Reorder the terms: 3 + x = -3.605551275 Solving 3 + x = -3.605551275 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = -3.605551275 + -3 Combine like terms: 3 + -3 = 0 0 + x = -3.605551275 + -3 x = -3.605551275 + -3 Combine like terms: -3.605551275 + -3 = -6.605551275 x = -6.605551275 Simplifying x = -6.605551275Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.605551275, -6.605551275}
