Simplifying 0 = -1x2 + 160x + -100 Reorder the terms: 0 = -100 + 160x + -1x2 Solving 0 = -100 + 160x + -1x2 Solving for variable 'x'. Combine like terms: 0 + 100 = 100 100 + -160x + x2 = -100 + 160x + -1x2 + 100 + -160x + x2 Reorder the terms: 100 + -160x + x2 = -100 + 100 + 160x + -160x + -1x2 + x2 Combine like terms: -100 + 100 = 0 100 + -160x + x2 = 0 + 160x + -160x + -1x2 + x2 100 + -160x + x2 = 160x + -160x + -1x2 + x2 Combine like terms: 160x + -160x = 0 100 + -160x + x2 = 0 + -1x2 + x2 100 + -160x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 100 + -160x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-100' to each side of the equation. 100 + -160x + -100 + x2 = 0 + -100 Reorder the terms: 100 + -100 + -160x + x2 = 0 + -100 Combine like terms: 100 + -100 = 0 0 + -160x + x2 = 0 + -100 -160x + x2 = 0 + -100 Combine like terms: 0 + -100 = -100 -160x + x2 = -100 The x term is -160x. Take half its coefficient (-80). Square it (6400) and add it to both sides. Add '6400' to each side of the equation. -160x + 6400 + x2 = -100 + 6400 Reorder the terms: 6400 + -160x + x2 = -100 + 6400 Combine like terms: -100 + 6400 = 6300 6400 + -160x + x2 = 6300 Factor a perfect square on the left side: (x + -80)(x + -80) = 6300 Calculate the square root of the right side: 79.372539332 Break this problem into two subproblems by setting (x + -80) equal to 79.372539332 and -79.372539332.Subproblem 1
x + -80 = 79.372539332 Simplifying x + -80 = 79.372539332 Reorder the terms: -80 + x = 79.372539332 Solving -80 + x = 79.372539332 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '80' to each side of the equation. -80 + 80 + x = 79.372539332 + 80 Combine like terms: -80 + 80 = 0 0 + x = 79.372539332 + 80 x = 79.372539332 + 80 Combine like terms: 79.372539332 + 80 = 159.372539332 x = 159.372539332 Simplifying x = 159.372539332Subproblem 2
x + -80 = -79.372539332 Simplifying x + -80 = -79.372539332 Reorder the terms: -80 + x = -79.372539332 Solving -80 + x = -79.372539332 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '80' to each side of the equation. -80 + 80 + x = -79.372539332 + 80 Combine like terms: -80 + 80 = 0 0 + x = -79.372539332 + 80 x = -79.372539332 + 80 Combine like terms: -79.372539332 + 80 = 0.627460668 x = 0.627460668 Simplifying x = 0.627460668Solution
The solution to the problem is based on the solutions from the subproblems. x = {159.372539332, 0.627460668}
