Simplifying (x2) + -6x + 6 = 48 x2 + -6x + 6 = 48 Reorder the terms: 6 + -6x + x2 = 48 Solving 6 + -6x + x2 = 48 Solving for variable 'x'. Reorder the terms: 6 + -48 + -6x + x2 = 48 + -48 Combine like terms: 6 + -48 = -42 -42 + -6x + x2 = 48 + -48 Combine like terms: 48 + -48 = 0 -42 + -6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '42' to each side of the equation. -42 + -6x + 42 + x2 = 0 + 42 Reorder the terms: -42 + 42 + -6x + x2 = 0 + 42 Combine like terms: -42 + 42 = 0 0 + -6x + x2 = 0 + 42 -6x + x2 = 0 + 42 Combine like terms: 0 + 42 = 42 -6x + x2 = 42 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = 42 + 9 Reorder the terms: 9 + -6x + x2 = 42 + 9 Combine like terms: 42 + 9 = 51 9 + -6x + x2 = 51 Factor a perfect square on the left side: (x + -3)(x + -3) = 51 Calculate the square root of the right side: 7.141428429 Break this problem into two subproblems by setting (x + -3) equal to 7.141428429 and -7.141428429.Subproblem 1
x + -3 = 7.141428429 Simplifying x + -3 = 7.141428429 Reorder the terms: -3 + x = 7.141428429 Solving -3 + x = 7.141428429 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = 7.141428429 + 3 Combine like terms: -3 + 3 = 0 0 + x = 7.141428429 + 3 x = 7.141428429 + 3 Combine like terms: 7.141428429 + 3 = 10.141428429 x = 10.141428429 Simplifying x = 10.141428429Subproblem 2
x + -3 = -7.141428429 Simplifying x + -3 = -7.141428429 Reorder the terms: -3 + x = -7.141428429 Solving -3 + x = -7.141428429 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = -7.141428429 + 3 Combine like terms: -3 + 3 = 0 0 + x = -7.141428429 + 3 x = -7.141428429 + 3 Combine like terms: -7.141428429 + 3 = -4.141428429 x = -4.141428429 Simplifying x = -4.141428429Solution
The solution to the problem is based on the solutions from the subproblems. x = {10.141428429, -4.141428429}
