Q. Write the equation in standard form for the ellipse 3x2+y2+2y−26=0.
Complete the square for y terms: Now, we complete the square for the y terms.To do this, we add and subtract (22)2, which is 1, inside the parentheses.3x2+(y2+2y+1−1)=26
Rewrite y terms as perfect square: We can now rewrite the y terms as a perfect square and simplify the equation.3x2+((y+1)2−1)=26
Add 1 to isolate perfect square: Next, we add 1 to both sides to isolate the perfect square on the left side.3x2+(y+1)2=27
Divide to get standard form: Now, we divide the entire equation by 27 to get the standard form of the ellipse.9x2 + 27(y+1)2 = 1
