Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Given: 2x2-xy-3y2+6x+y+4=0 First, we will find the separate equations. 2x2-xy-3y2=0 ⇒2x2-xy+2xy-2xy-3y2=0 ⇒x+y2x-3y=0 Now, m & l be the constants term in the above equations. x+y+m=0 2x-3y+l=0 Then, 2x2-xy-3y2+6x+y+4=x+y+m2x-3y+l On comparing the…
