Simplifying x2 + -3x + -77 = 0 Reorder the terms: -77 + -3x + x2 = 0 Solving -77 + -3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '77' to each side of the equation. -77 + -3x + 77 + x2 = 0 + 77 Reorder the terms: -77 + 77 + -3x + x2 = 0 + 77 Combine like terms: -77 + 77 = 0 0 + -3x + x2 = 0 + 77 -3x + x2 = 0 + 77 Combine like terms: 0 + 77 = 77 -3x + x2 = 77 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = 77 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 77 + 2.25 Combine like terms: 77 + 2.25 = 79.25 2.25 + -3x + x2 = 79.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 79.25 Calculate the square root of the right side: 8.902246907 Break this problem into two subproblems by setting (x + -1.5) equal to 8.902246907 and -8.902246907.Subproblem 1
x + -1.5 = 8.902246907 Simplifying x + -1.5 = 8.902246907 Reorder the terms: -1.5 + x = 8.902246907 Solving -1.5 + x = 8.902246907 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 8.902246907 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 8.902246907 + 1.5 x = 8.902246907 + 1.5 Combine like terms: 8.902246907 + 1.5 = 10.402246907 x = 10.402246907 Simplifying x = 10.402246907Subproblem 2
x + -1.5 = -8.902246907 Simplifying x + -1.5 = -8.902246907 Reorder the terms: -1.5 + x = -8.902246907 Solving -1.5 + x = -8.902246907 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -8.902246907 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -8.902246907 + 1.5 x = -8.902246907 + 1.5 Combine like terms: -8.902246907 + 1.5 = -7.402246907 x = -7.402246907 Simplifying x = -7.402246907Solution
