Simplifying x2 + 24x = 12 Reorder the terms: 24x + x2 = 12 Solving 24x + x2 = 12 Solving for variable 'x'. Reorder the terms: -12 + 24x + x2 = 12 + -12 Combine like terms: 12 + -12 = 0 -12 + 24x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '12' to each side of the equation. -12 + 24x + 12 + x2 = 0 + 12 Reorder the terms: -12 + 12 + 24x + x2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + 24x + x2 = 0 + 12 24x + x2 = 0 + 12 Combine like terms: 0 + 12 = 12 24x + x2 = 12 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 = 12 + 144 Reorder the terms: 144 + 24x + x2 = 12 + 144 Combine like terms: 12 + 144 = 156 144 + 24x + x2 = 156 Factor a perfect square on the left side: (x + 12)(x + 12) = 156 Calculate the square root of the right side: 12.489995997 Break this problem into two subproblems by setting (x + 12) equal to 12.489995997 and -12.489995997.Subproblem 1
x + 12 = 12.489995997 Simplifying x + 12 = 12.489995997 Reorder the terms: 12 + x = 12.489995997 Solving 12 + x = 12.489995997 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 = 12.489995997 + -12 Combine like terms: 12 + -12 = 0 0 + x = 12.489995997 + -12 x = 12.489995997 + -12 Combine like terms: 12.489995997 + -12 = 0.489995997 x = 0.489995997 Simplifying x = 0.489995997Subproblem 2
x + 12 = -12.489995997 Simplifying x + 12 = -12.489995997 Reorder the terms: 12 + x = -12.489995997 Solving 12 + x = -12.489995997 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 = -12.489995997 + -12 Combine like terms: 12 + -12 = 0 0 + x = -12.489995997 + -12 x = -12.489995997 + -12 Combine like terms: -12.489995997 + -12 = -24.489995997 x = -24.489995997 Simplifying x = -24.489995997Solution
