Download Solution PDFఇవ్వబడినది,
(x - 1) 2 + (y - 2) 2 = (x – 1) (y - 2)
కాన్సెప్ట్/సూత్రం:
(x – y) 2 = k 2
(x – y) = k లేదా (–k)
x = (k + y) లేదా (y – k)
గణన:
(x -1) 2 + (y - 2) 2 = (x – 1) (y - 2)
⇒ (x – 1) 2 = (x – 1) (y – 2)
⇒ (x – 1) = (y – 2)
⇒ x – y = -2 + 1
⇒ x – y = (-1) ----(1)
⇒ (y – 2) 2 = (x – 1) (y – 2)
⇒ (y – 2) = (x – 1)
⇒ x – y = -2 + 1
⇒ x – y = (-1) ----(2)
y = 2 మరియు x = 1,
⇒ 1 – 2 = (-1)
(-1) = (-1) (సంతృప్తం)
ఇప్పుడు,
2x + 3y
⇒ 2 × 1 + 3 × 2
⇒ 2 + 6
⇒ 8
