Simplifying x2 + -21x + -36 = 0 Reorder the terms: -36 + -21x + x2 = 0 Solving -36 + -21x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '36' to each side of the equation. -36 + -21x + 36 + x2 = 0 + 36 Reorder the terms: -36 + 36 + -21x + x2 = 0 + 36 Combine like terms: -36 + 36 = 0 0 + -21x + x2 = 0 + 36 -21x + x2 = 0 + 36 Combine like terms: 0 + 36 = 36 -21x + x2 = 36 The x term is -21x. Take half its coefficient (-10.5). Square it (110.25) and add it to both sides. Add '110.25' to each side of the equation. -21x + 110.25 + x2 = 36 + 110.25 Reorder the terms: 110.25 + -21x + x2 = 36 + 110.25 Combine like terms: 36 + 110.25 = 146.25 110.25 + -21x + x2 = 146.25 Factor a perfect square on the left side: (x + -10.5)(x + -10.5) = 146.25 Calculate the square root of the right side: 12.093386622 Break this problem into two subproblems by setting (x + -10.5) equal to 12.093386622 and -12.093386622.Subproblem 1
x + -10.5 = 12.093386622 Simplifying x + -10.5 = 12.093386622 Reorder the terms: -10.5 + x = 12.093386622 Solving -10.5 + x = 12.093386622 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10.5' to each side of the equation. -10.5 + 10.5 + x = 12.093386622 + 10.5 Combine like terms: -10.5 + 10.5 = 0.0 0.0 + x = 12.093386622 + 10.5 x = 12.093386622 + 10.5 Combine like terms: 12.093386622 + 10.5 = 22.593386622 x = 22.593386622 Simplifying x = 22.593386622Subproblem 2
x + -10.5 = -12.093386622 Simplifying x + -10.5 = -12.093386622 Reorder the terms: -10.5 + x = -12.093386622 Solving -10.5 + x = -12.093386622 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10.5' to each side of the equation. -10.5 + 10.5 + x = -12.093386622 + 10.5 Combine like terms: -10.5 + 10.5 = 0.0 0.0 + x = -12.093386622 + 10.5 x = -12.093386622 + 10.5 Combine like terms: -12.093386622 + 10.5 = -1.593386622 x = -1.593386622 Simplifying x = -1.593386622Solution
The solution to the problem is based on the solutions from the subproblems. x = {22.593386622, -1.593386622}
