Question

Find the lengths and equations of axes of the conics :
(i) 5x2 - 6xy + 5y2 + 22x - 26y + 29 = 0
ii) x2 - 5xy + y2 + 8x – 20y +15 = 0​

Answer 1

Answer:

ANSWER

Centre of ellipse is (

δx

δs

=0,

δy

δs

=0)

δx

δs

=0⇒10x−6y+22=0

δy

δs

=0⇒10y−6x−26=0

Solving both eqns

⇒x=−1;y=2

∴centre is (−1,2)
