Question

11 Add:
2x – 3xy – 5y' By – 3 xy + 2х​

Answer 1

Answer:

28

Step-by-step explanation:

$Comparing the equation with the standard form ax 2 +2hxy+by 2 +2gx+2fy+c=0a=2,h=− 23​ ,b=5,g=3,f=− 23​ ,c=5Δ=abc+2fgh−af 2 −bg 2 −ch 2 =(2)(5)(5)+2(− 23​ )(3)(− 23​ )−(2)(− 23​ ) 2 −(5)(3) 2 −(5)(− 23​ ) 2 =50+ 227​ − 29​ −45− 4225​ =− 4169​ =0Descriminant =h 2 −ab=(− 23​ ) 2 −(2)(5)= 49​ −10= 4−31​ <0So, the curve represents either a circle or an ellipsea=b and a+bΔ​ = 2+5− 4169​ ​ =− 28$
