The following problem's solution has a mistake.
a. On what row does the mistake occur? Justify your answer in words.
Select the "Insert" drop-down option in the menu below and use "VI Equation" to type your
answer when you need to incorporate symbols, equations, or other math expressions.
Problem: Convert the following equation to standard form:
25у - 9х2 - 50у — 54х — 281 — 0
Solution:
Row 1: 25 y – 50y – 9x² – 54x = 281
Row 2: 25 (y - 2y) – 9 (x² – 6x) = 281
Row 3: 25 (y – 2y + 1) – 9 (x² – 6x +9) = 281 + 25 – 81
Row 4: 25(y — 1)? — 9(х — 3)? %3D 225
