### Section 4-3 : Ellipses

For problems 1 – 3 sketch the ellipse.

1. $$\displaystyle \frac{{{{\left( {x + 3} \right)}^2}}}{9} + \frac{{{{\left( {y - 5} \right)}^2}}}{3} = 1$$ Solution
2. $$\displaystyle {x^2} + \frac{{{{\left( {y - 1} \right)}^2}}}{4} = 1$$ Solution
3. $$\displaystyle 4{\left( {x + 2} \right)^2} + \frac{{{{\left( {y + 4} \right)}^2}}}{4} = 1$$ Solution

For problems 4 & 5 complete the square on the $$x$$ and $$y$$ portions of the equation and write the equation into the standard form of the equation of the ellipse.

1. $${x^2} + 8x + 3{y^2} - 6y + 7 = 0$$ Solution
2. $$9{x^2} + 126x + 4{y^2} - 32y + 469 = 0$$ Solution
