Simplifying x2 + -3x + -35 = 0 Reorder the terms: -35 + -3x + x2 = 0 Solving -35 + -3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '35' to each side of the equation. -35 + -3x + 35 + x2 = 0 + 35 Reorder the terms: -35 + 35 + -3x + x2 = 0 + 35 Combine like terms: -35 + 35 = 0 0 + -3x + x2 = 0 + 35 -3x + x2 = 0 + 35 Combine like terms: 0 + 35 = 35 -3x + x2 = 35 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 = 35 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 35 + 2.25 Combine like terms: 35 + 2.25 = 37.25 2.25 + -3x + x2 = 37.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 37.25 Calculate the square root of the right side: 6.103277808 Break this problem into two subproblems by setting (x + -1.5) equal to 6.103277808 and -6.103277808.Subproblem 1
x + -1.5 = 6.103277808 Simplifying x + -1.5 = 6.103277808 Reorder the terms: -1.5 + x = 6.103277808 Solving -1.5 + x = 6.103277808 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 = 6.103277808 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 6.103277808 + 1.5 x = 6.103277808 + 1.5 Combine like terms: 6.103277808 + 1.5 = 7.603277808 x = 7.603277808 Simplifying x = 7.603277808Subproblem 2
x + -1.5 = -6.103277808 Simplifying x + -1.5 = -6.103277808 Reorder the terms: -1.5 + x = -6.103277808 Solving -1.5 + x = -6.103277808 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 = -6.103277808 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -6.103277808 + 1.5 x = -6.103277808 + 1.5 Combine like terms: -6.103277808 + 1.5 = -4.603277808 x = -4.603277808 Simplifying x = -4.603277808Solution
