Simplifying x * x + 14x + 15 = 0 Multiply x * x x2 + 14x + 15 = 0 Reorder the terms: 15 + 14x + x2 = 0 Solving 15 + 14x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-15' to each side of the equation. 15 + 14x + -15 + x2 = 0 + -15 Reorder the terms: 15 + -15 + 14x + x2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + 14x + x2 = 0 + -15 14x + x2 = 0 + -15 Combine like terms: 0 + -15 = -15 14x + x2 = -15 The x term is 14x. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14x + 49 + x2 = -15 + 49 Reorder the terms: 49 + 14x + x2 = -15 + 49 Combine like terms: -15 + 49 = 34 49 + 14x + x2 = 34 Factor a perfect square on the left side: (x + 7)(x + 7) = 34 Calculate the square root of the right side: 5.830951895 Break this problem into two subproblems by setting (x + 7) equal to 5.830951895 and -5.830951895.Subproblem 1
x + 7 = 5.830951895 Simplifying x + 7 = 5.830951895 Reorder the terms: 7 + x = 5.830951895 Solving 7 + x = 5.830951895 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = 5.830951895 + -7 Combine like terms: 7 + -7 = 0 0 + x = 5.830951895 + -7 x = 5.830951895 + -7 Combine like terms: 5.830951895 + -7 = -1.169048105 x = -1.169048105 Simplifying x = -1.169048105Subproblem 2
x + 7 = -5.830951895 Simplifying x + 7 = -5.830951895 Reorder the terms: 7 + x = -5.830951895 Solving 7 + x = -5.830951895 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = -5.830951895 + -7 Combine like terms: 7 + -7 = 0 0 + x = -5.830951895 + -7 x = -5.830951895 + -7 Combine like terms: -5.830951895 + -7 = -12.830951895 x = -12.830951895 Simplifying x = -12.830951895Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.169048105, -12.830951895}
