Simplifying x2 + 12x = 3.69 Reorder the terms: 12x + x2 = 3.69 Solving 12x + x2 = 3.69 Solving for variable 'x'. Reorder the terms: -3.69 + 12x + x2 = 3.69 + -3.69 Combine like terms: 3.69 + -3.69 = 0.00 -3.69 + 12x + x2 = 0.00 Begin completing the square. Move the constant term to the right: Add '3.69' to each side of the equation. -3.69 + 12x + 3.69 + x2 = 0.00 + 3.69 Reorder the terms: -3.69 + 3.69 + 12x + x2 = 0.00 + 3.69 Combine like terms: -3.69 + 3.69 = 0.00 0.00 + 12x + x2 = 0.00 + 3.69 12x + x2 = 0.00 + 3.69 Combine like terms: 0.00 + 3.69 = 3.69 12x + x2 = 3.69 The x term is 12x. Take half its coefficient (6). Square it (36) and add it to both sides. Add '36' to each side of the equation. 12x + 36 + x2 = 3.69 + 36 Reorder the terms: 36 + 12x + x2 = 3.69 + 36 Combine like terms: 3.69 + 36 = 39.69 36 + 12x + x2 = 39.69 Factor a perfect square on the left side: (x + 6)(x + 6) = 39.69 Calculate the square root of the right side: 6.3 Break this problem into two subproblems by setting (x + 6) equal to 6.3 and -6.3.Subproblem 1
x + 6 = 6.3 Simplifying x + 6 = 6.3 Reorder the terms: 6 + x = 6.3 Solving 6 + x = 6.3 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x = 6.3 + -6 Combine like terms: 6 + -6 = 0 0 + x = 6.3 + -6 x = 6.3 + -6 Combine like terms: 6.3 + -6 = 0.3 x = 0.3 Simplifying x = 0.3Subproblem 2
x + 6 = -6.3 Simplifying x + 6 = -6.3 Reorder the terms: 6 + x = -6.3 Solving 6 + x = -6.3 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x = -6.3 + -6 Combine like terms: 6 + -6 = 0 0 + x = -6.3 + -6 x = -6.3 + -6 Combine like terms: -6.3 + -6 = -12.3 x = -12.3 Simplifying x = -12.3Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.3, -12.3}
