Simplifying x2 + -30x + -1 = 0 Reorder the terms: -1 + -30x + x2 = 0 Solving -1 + -30x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + -30x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -30x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -30x + x2 = 0 + 1 -30x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -30x + x2 = 1 The x term is -30x. Take half its coefficient (-15). Square it (225) and add it to both sides. Add '225' to each side of the equation. -30x + 225 + x2 = 1 + 225 Reorder the terms: 225 + -30x + x2 = 1 + 225 Combine like terms: 1 + 225 = 226 225 + -30x + x2 = 226 Factor a perfect square on the left side: (x + -15)(x + -15) = 226 Calculate the square root of the right side: 15.033296378 Break this problem into two subproblems by setting (x + -15) equal to 15.033296378 and -15.033296378.Subproblem 1
x + -15 = 15.033296378 Simplifying x + -15 = 15.033296378 Reorder the terms: -15 + x = 15.033296378 Solving -15 + x = 15.033296378 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '15' to each side of the equation. -15 + 15 + x = 15.033296378 + 15 Combine like terms: -15 + 15 = 0 0 + x = 15.033296378 + 15 x = 15.033296378 + 15 Combine like terms: 15.033296378 + 15 = 30.033296378 x = 30.033296378 Simplifying x = 30.033296378Subproblem 2
