Simplifying x2 + -15x + -10000 = 0 Reorder the terms: -10000 + -15x + x2 = 0 Solving -10000 + -15x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '10000' to each side of the equation. -10000 + -15x + 10000 + x2 = 0 + 10000 Reorder the terms: -10000 + 10000 + -15x + x2 = 0 + 10000 Combine like terms: -10000 + 10000 = 0 0 + -15x + x2 = 0 + 10000 -15x + x2 = 0 + 10000 Combine like terms: 0 + 10000 = 10000 -15x + x2 = 10000 The x term is -15x. Take half its coefficient (-7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. -15x + 56.25 + x2 = 10000 + 56.25 Reorder the terms: 56.25 + -15x + x2 = 10000 + 56.25 Combine like terms: 10000 + 56.25 = 10056.25 56.25 + -15x + x2 = 10056.25 Factor a perfect square on the left side: (x + -7.5)(x + -7.5) = 10056.25 Calculate the square root of the right side: 100.280855601 Break this problem into two subproblems by setting (x + -7.5) equal to 100.280855601 and -100.280855601.Subproblem 1
x + -7.5 = 100.280855601 Simplifying x + -7.5 = 100.280855601 Reorder the terms: -7.5 + x = 100.280855601 Solving -7.5 + x = 100.280855601 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + x = 100.280855601 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = 100.280855601 + 7.5 x = 100.280855601 + 7.5 Combine like terms: 100.280855601 + 7.5 = 107.780855601 x = 107.780855601 Simplifying x = 107.780855601Subproblem 2
x + -7.5 = -100.280855601 Simplifying x + -7.5 = -100.280855601 Reorder the terms: -7.5 + x = -100.280855601 Solving -7.5 + x = -100.280855601 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + x = -100.280855601 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = -100.280855601 + 7.5 x = -100.280855601 + 7.5 Combine like terms: -100.280855601 + 7.5 = -92.780855601 x = -92.780855601 Simplifying x = -92.780855601Solution
