Simplifying 0 = x2 + -17x + -225 Reorder the terms: 0 = -225 + -17x + x2 Solving 0 = -225 + -17x + x2 Solving for variable 'x'. Combine like terms: 0 + 225 = 225 225 + 17x + -1x2 = -225 + -17x + x2 + 225 + 17x + -1x2 Reorder the terms: 225 + 17x + -1x2 = -225 + 225 + -17x + 17x + x2 + -1x2 Combine like terms: -225 + 225 = 0 225 + 17x + -1x2 = 0 + -17x + 17x + x2 + -1x2 225 + 17x + -1x2 = -17x + 17x + x2 + -1x2 Combine like terms: -17x + 17x = 0 225 + 17x + -1x2 = 0 + x2 + -1x2 225 + 17x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 225 + 17x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -225 + -17x + x2 = 0 Move the constant term to the right: Add '225' to each side of the equation. -225 + -17x + 225 + x2 = 0 + 225 Reorder the terms: -225 + 225 + -17x + x2 = 0 + 225 Combine like terms: -225 + 225 = 0 0 + -17x + x2 = 0 + 225 -17x + x2 = 0 + 225 Combine like terms: 0 + 225 = 225 -17x + x2 = 225 The x term is -17x. Take half its coefficient (-8.5). Square it (72.25) and add it to both sides. Add '72.25' to each side of the equation. -17x + 72.25 + x2 = 225 + 72.25 Reorder the terms: 72.25 + -17x + x2 = 225 + 72.25 Combine like terms: 225 + 72.25 = 297.25 72.25 + -17x + x2 = 297.25 Factor a perfect square on the left side: (x + -8.5)(x + -8.5) = 297.25 Calculate the square root of the right side: 17.24093965 Break this problem into two subproblems by setting (x + -8.5) equal to 17.24093965 and -17.24093965.Subproblem 1
x + -8.5 = 17.24093965 Simplifying x + -8.5 = 17.24093965 Reorder the terms: -8.5 + x = 17.24093965 Solving -8.5 + x = 17.24093965 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '8.5' to each side of the equation. -8.5 + 8.5 + x = 17.24093965 + 8.5 Combine like terms: -8.5 + 8.5 = 0.0 0.0 + x = 17.24093965 + 8.5 x = 17.24093965 + 8.5 Combine like terms: 17.24093965 + 8.5 = 25.74093965 x = 25.74093965 Simplifying x = 25.74093965Subproblem 2
