Simplifying 90 * 10z = 8100 + 100 + z2 Multiply 90 * 10 900z = 8100 + 100 + z2 Combine like terms: 8100 + 100 = 8200 900z = 8200 + z2 Solving 900z = 8200 + z2 Solving for variable 'z'. Reorder the terms: -8200 + 900z + -1z2 = 8200 + z2 + -8200 + -1z2 Reorder the terms: -8200 + 900z + -1z2 = 8200 + -8200 + z2 + -1z2 Combine like terms: 8200 + -8200 = 0 -8200 + 900z + -1z2 = 0 + z2 + -1z2 -8200 + 900z + -1z2 = z2 + -1z2 Combine like terms: z2 + -1z2 = 0 -8200 + 900z + -1z2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 8200 + -900z + z2 = 0 Move the constant term to the right: Add '-8200' to each side of the equation. 8200 + -900z + -8200 + z2 = 0 + -8200 Reorder the terms: 8200 + -8200 + -900z + z2 = 0 + -8200 Combine like terms: 8200 + -8200 = 0 0 + -900z + z2 = 0 + -8200 -900z + z2 = 0 + -8200 Combine like terms: 0 + -8200 = -8200 -900z + z2 = -8200 The z term is -900z. Take half its coefficient (-450). Square it (202500) and add it to both sides. Add '202500' to each side of the equation. -900z + 202500 + z2 = -8200 + 202500 Reorder the terms: 202500 + -900z + z2 = -8200 + 202500 Combine like terms: -8200 + 202500 = 194300 202500 + -900z + z2 = 194300 Factor a perfect square on the left side: (z + -450)(z + -450) = 194300 Calculate the square root of the right side: 440.794736811 Break this problem into two subproblems by setting (z + -450) equal to 440.794736811 and -440.794736811.Subproblem 1
z + -450 = 440.794736811 Simplifying z + -450 = 440.794736811 Reorder the terms: -450 + z = 440.794736811 Solving -450 + z = 440.794736811 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '450' to each side of the equation. -450 + 450 + z = 440.794736811 + 450 Combine like terms: -450 + 450 = 0 0 + z = 440.794736811 + 450 z = 440.794736811 + 450 Combine like terms: 440.794736811 + 450 = 890.794736811 z = 890.794736811 Simplifying z = 890.794736811Subproblem 2
z + -450 = -440.794736811 Simplifying z + -450 = -440.794736811 Reorder the terms: -450 + z = -440.794736811 Solving -450 + z = -440.794736811 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '450' to each side of the equation. -450 + 450 + z = -440.794736811 + 450 Combine like terms: -450 + 450 = 0 0 + z = -440.794736811 + 450 z = -440.794736811 + 450 Combine like terms: -440.794736811 + 450 = 9.205263189 z = 9.205263189 Simplifying z = 9.205263189Solution
