Simplifying x2 + -16x + -2 = -30x Reorder the terms: -2 + -16x + x2 = -30x Solving -2 + -16x + x2 = -30x Solving for variable 'x'. Reorder the terms: -2 + -16x + 30x + x2 = -30x + 30x Combine like terms: -16x + 30x = 14x -2 + 14x + x2 = -30x + 30x Combine like terms: -30x + 30x = 0 -2 + 14x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '2' to each side of the equation. -2 + 14x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 14x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 14x + x2 = 0 + 2 14x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 14x + x2 = 2 The x term is 14x. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14x + 49 + x2 = 2 + 49 Reorder the terms: 49 + 14x + x2 = 2 + 49 Combine like terms: 2 + 49 = 51 49 + 14x + x2 = 51 Factor a perfect square on the left side: (x + 7)(x + 7) = 51 Calculate the square root of the right side: 7.141428429 Break this problem into two subproblems by setting (x + 7) equal to 7.141428429 and -7.141428429.Subproblem 1
x + 7 = 7.141428429 Simplifying x + 7 = 7.141428429 Reorder the terms: 7 + x = 7.141428429 Solving 7 + x = 7.141428429 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = 7.141428429 + -7 Combine like terms: 7 + -7 = 0 0 + x = 7.141428429 + -7 x = 7.141428429 + -7 Combine like terms: 7.141428429 + -7 = 0.141428429 x = 0.141428429 Simplifying x = 0.141428429Subproblem 2
x + 7 = -7.141428429 Simplifying x + 7 = -7.141428429 Reorder the terms: 7 + x = -7.141428429 Solving 7 + x = -7.141428429 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = -7.141428429 + -7 Combine like terms: 7 + -7 = 0 0 + x = -7.141428429 + -7 x = -7.141428429 + -7 Combine like terms: -7.141428429 + -7 = -14.141428429 x = -14.141428429 Simplifying x = -14.141428429Solution
