Simplifying x2 + -28x + -2 = -50 Reorder the terms: -2 + -28x + x2 = -50 Solving -2 + -28x + x2 = -50 Solving for variable 'x'. Reorder the terms: -2 + 50 + -28x + x2 = -50 + 50 Combine like terms: -2 + 50 = 48 48 + -28x + x2 = -50 + 50 Combine like terms: -50 + 50 = 0 48 + -28x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-48' to each side of the equation. 48 + -28x + -48 + x2 = 0 + -48 Reorder the terms: 48 + -48 + -28x + x2 = 0 + -48 Combine like terms: 48 + -48 = 0 0 + -28x + x2 = 0 + -48 -28x + x2 = 0 + -48 Combine like terms: 0 + -48 = -48 -28x + x2 = -48 The x term is -28x. Take half its coefficient (-14). Square it (196) and add it to both sides. Add '196' to each side of the equation. -28x + 196 + x2 = -48 + 196 Reorder the terms: 196 + -28x + x2 = -48 + 196 Combine like terms: -48 + 196 = 148 196 + -28x + x2 = 148 Factor a perfect square on the left side: (x + -14)(x + -14) = 148 Calculate the square root of the right side: 12.165525061 Break this problem into two subproblems by setting (x + -14) equal to 12.165525061 and -12.165525061.Subproblem 1
x + -14 = 12.165525061 Simplifying x + -14 = 12.165525061 Reorder the terms: -14 + x = 12.165525061 Solving -14 + x = 12.165525061 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '14' to each side of the equation. -14 + 14 + x = 12.165525061 + 14 Combine like terms: -14 + 14 = 0 0 + x = 12.165525061 + 14 x = 12.165525061 + 14 Combine like terms: 12.165525061 + 14 = 26.165525061 x = 26.165525061 Simplifying x = 26.165525061Subproblem 2
x + -14 = -12.165525061 Simplifying x + -14 = -12.165525061 Reorder the terms: -14 + x = -12.165525061 Solving -14 + x = -12.165525061 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '14' to each side of the equation. -14 + 14 + x = -12.165525061 + 14 Combine like terms: -14 + 14 = 0 0 + x = -12.165525061 + 14 x = -12.165525061 + 14 Combine like terms: -12.165525061 + 14 = 1.834474939 x = 1.834474939 Simplifying x = 1.834474939Solution
