Answer:
<em>The foci of the given ellipse = (0 ,-√5 ) and ( 0, √5 )</em>
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given Ellipse 9 x² + 4 y² = 36
⇒
<u><em>Step(ii)</em></u>:-
The Major axis lies on y-axis
<em> Foci of the Formula C² = a² -b² = 9-4 =5</em>
<em> C = √5 </em>
The Foci is always lie on the major axis(longest) axis, spaced equally each side of the centre
<em>Given ellipse of the foci is lie on Y- axis</em>
<u><em>Final answer</em></u><em>:-</em>
<em>The foci of the given ellipse = (0 ,-√5 ) and ( 0, √5 )</em>
X=2
You have to first distribute the two and then you have to move the variable to one side of the equation and the number to the other. The work is attached below
