Simplifying x2 + -20x + 12 = 0 Reorder the terms: 12 + -20x + x2 = 0 Solving 12 + -20x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-12' to each side of the equation. 12 + -20x + -12 + x2 = 0 + -12 Reorder the terms: 12 + -12 + -20x + x2 = 0 + -12 Combine like terms: 12 + -12 = 0 0 + -20x + x2 = 0 + -12 -20x + x2 = 0 + -12 Combine like terms: 0 + -12 = -12 -20x + x2 = -12 The x term is -20x. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20x + 100 + x2 = -12 + 100 Reorder the terms: 100 + -20x + x2 = -12 + 100 Combine like terms: -12 + 100 = 88 100 + -20x + x2 = 88 Factor a perfect square on the left side: (x + -10)(x + -10) = 88 Calculate the square root of the right side: 9.38083152 Break this problem into two subproblems by setting (x + -10) equal to 9.38083152 and -9.38083152.Subproblem 1
x + -10 = 9.38083152 Simplifying x + -10 = 9.38083152 Reorder the terms: -10 + x = 9.38083152 Solving -10 + x = 9.38083152 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + x = 9.38083152 + 10 Combine like terms: -10 + 10 = 0 0 + x = 9.38083152 + 10 x = 9.38083152 + 10 Combine like terms: 9.38083152 + 10 = 19.38083152 x = 19.38083152 Simplifying x = 19.38083152Subproblem 2
x + -10 = -9.38083152 Simplifying x + -10 = -9.38083152 Reorder the terms: -10 + x = -9.38083152 Solving -10 + x = -9.38083152 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + x = -9.38083152 + 10 Combine like terms: -10 + 10 = 0 0 + x = -9.38083152 + 10 x = -9.38083152 + 10 Combine like terms: -9.38083152 + 10 = 0.61916848 x = 0.61916848 Simplifying x = 0.61916848Solution
The solution to the problem is based on the solutions from the subproblems. x = {19.38083152, 0.61916848}
