Simplifying x2 + -5x = 100 Reorder the terms: -5x + x2 = 100 Solving -5x + x2 = 100 Solving for variable 'x'. Reorder the terms: -100 + -5x + x2 = 100 + -100 Combine like terms: 100 + -100 = 0 -100 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '100' to each side of the equation. -100 + -5x + 100 + x2 = 0 + 100 Reorder the terms: -100 + 100 + -5x + x2 = 0 + 100 Combine like terms: -100 + 100 = 0 0 + -5x + x2 = 0 + 100 -5x + x2 = 0 + 100 Combine like terms: 0 + 100 = 100 -5x + x2 = 100 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = 100 + 6.25 Reorder the terms: 6.25 + -5x + x2 = 100 + 6.25 Combine like terms: 100 + 6.25 = 106.25 6.25 + -5x + x2 = 106.25 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 106.25 Calculate the square root of the right side: 10.307764064 Break this problem into two subproblems by setting (x + -2.5) equal to 10.307764064 and -10.307764064.Subproblem 1
x + -2.5 = 10.307764064 Simplifying x + -2.5 = 10.307764064 Reorder the terms: -2.5 + x = 10.307764064 Solving -2.5 + x = 10.307764064 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 10.307764064 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 10.307764064 + 2.5 x = 10.307764064 + 2.5 Combine like terms: 10.307764064 + 2.5 = 12.807764064 x = 12.807764064 Simplifying x = 12.807764064Subproblem 2
x + -2.5 = -10.307764064 Simplifying x + -2.5 = -10.307764064 Reorder the terms: -2.5 + x = -10.307764064 Solving -2.5 + x = -10.307764064 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -10.307764064 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -10.307764064 + 2.5 x = -10.307764064 + 2.5 Combine like terms: -10.307764064 + 2.5 = -7.807764064 x = -7.807764064 Simplifying x = -7.807764064Solution
