3 x 3 - ( (-1)^2 - 2)^2

Start evaluating the one in the most inner bracket:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1 - 2)^2

There is one more bracket, so we do what is in the bracket:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1-  2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1

Between x and -, we do the x first:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1-  2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
= 9 - 1

Then we do the -:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1-  2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
= 9 - 1
= 8

In an ellipse, the ratio of the distance between the foci and the length of the major axis is called:

Anni [7]

The ratio of the distance between the foci and the length of the <em>major</em> axis is called eccentricity.

<h3>Definitions of dimensions in ellipses</h3>

Dimensionally speaking, an ellipse is characterized by three variables:

Length of the <em>major</em> semiaxis ( $a$ ).
Length of the <em>minor</em> semiaxis ( $b$ ).
Distance between the foci and the center of the ellipse ( $c$ ).

And there is the following relationship:

$c = \sqrt{a^{2}-b^{2}}$ (1)

Another variable that measure how "similar" is an ellipse to a circle is the eccentricity ( $e$ ), which is defined by the following formula:

$e = \frac{c}{a}$ , $0 \ge c \ge 1$ (2)

The greater the eccentricity, the more similar the ellipse to a circle.

Therefore, the ratio of the distance between the foci and the length of the <em>major</em> axis is called eccentricity. $\blacksquare$
