Simplifying 0 = x2 + 8x + -163 Reorder the terms: 0 = -163 + 8x + x2 Solving 0 = -163 + 8x + x2 Solving for variable 'x'. Combine like terms: 0 + 163 = 163 163 + -8x + -1x2 = -163 + 8x + x2 + 163 + -8x + -1x2 Reorder the terms: 163 + -8x + -1x2 = -163 + 163 + 8x + -8x + x2 + -1x2 Combine like terms: -163 + 163 = 0 163 + -8x + -1x2 = 0 + 8x + -8x + x2 + -1x2 163 + -8x + -1x2 = 8x + -8x + x2 + -1x2 Combine like terms: 8x + -8x = 0 163 + -8x + -1x2 = 0 + x2 + -1x2 163 + -8x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 163 + -8x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -163 + 8x + x2 = 0 Move the constant term to the right: Add '163' to each side of the equation. -163 + 8x + 163 + x2 = 0 + 163 Reorder the terms: -163 + 163 + 8x + x2 = 0 + 163 Combine like terms: -163 + 163 = 0 0 + 8x + x2 = 0 + 163 8x + x2 = 0 + 163 Combine like terms: 0 + 163 = 163 8x + x2 = 163 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = 163 + 16 Reorder the terms: 16 + 8x + x2 = 163 + 16 Combine like terms: 163 + 16 = 179 16 + 8x + x2 = 179 Factor a perfect square on the left side: (x + 4)(x + 4) = 179 Calculate the square root of the right side: 13.37908816 Break this problem into two subproblems by setting (x + 4) equal to 13.37908816 and -13.37908816.Subproblem 1
x + 4 = 13.37908816 Simplifying x + 4 = 13.37908816 Reorder the terms: 4 + x = 13.37908816 Solving 4 + x = 13.37908816 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 13.37908816 + -4 Combine like terms: 4 + -4 = 0 0 + x = 13.37908816 + -4 x = 13.37908816 + -4 Combine like terms: 13.37908816 + -4 = 9.37908816 x = 9.37908816 Simplifying x = 9.37908816Subproblem 2
x + 4 = -13.37908816 Simplifying x + 4 = -13.37908816 Reorder the terms: 4 + x = -13.37908816 Solving 4 + x = -13.37908816 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = -13.37908816 + -4 Combine like terms: 4 + -4 = 0 0 + x = -13.37908816 + -4 x = -13.37908816 + -4 Combine like terms: -13.37908816 + -4 = -17.37908816 x = -17.37908816 Simplifying x = -17.37908816Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.37908816, -17.37908816}
