Simplifying x2 + 24x + -30 = 0 Reorder the terms: -30 + 24x + x2 = 0 Solving -30 + 24x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '30' to each side of the equation. -30 + 24x + 30 + x2 = 0 + 30 Reorder the terms: -30 + 30 + 24x + x2 = 0 + 30 Combine like terms: -30 + 30 = 0 0 + 24x + x2 = 0 + 30 24x + x2 = 0 + 30 Combine like terms: 0 + 30 = 30 24x + x2 = 30 The x term is 24x. Take half its coefficient (12). Square it (144) and add it to both sides. Add '144' to each side of the equation. 24x + 144 + x2 = 30 + 144 Reorder the terms: 144 + 24x + x2 = 30 + 144 Combine like terms: 30 + 144 = 174 144 + 24x + x2 = 174 Factor a perfect square on the left side: (x + 12)(x + 12) = 174 Calculate the square root of the right side: 13.190905958 Break this problem into two subproblems by setting (x + 12) equal to 13.190905958 and -13.190905958.Subproblem 1
x + 12 = 13.190905958 Simplifying x + 12 = 13.190905958 Reorder the terms: 12 + x = 13.190905958 Solving 12 + x = 13.190905958 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + x = 13.190905958 + -12 Combine like terms: 12 + -12 = 0 0 + x = 13.190905958 + -12 x = 13.190905958 + -12 Combine like terms: 13.190905958 + -12 = 1.190905958 x = 1.190905958 Simplifying x = 1.190905958Subproblem 2
x + 12 = -13.190905958 Simplifying x + 12 = -13.190905958 Reorder the terms: 12 + x = -13.190905958 Solving 12 + x = -13.190905958 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + x = -13.190905958 + -12 Combine like terms: 12 + -12 = 0 0 + x = -13.190905958 + -12 x = -13.190905958 + -12 Combine like terms: -13.190905958 + -12 = -25.190905958 x = -25.190905958 Simplifying x = -25.190905958Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.190905958, -25.190905958}
