$\frac{9}{4}$

Step-by-step explanation:

Given

x² + 3x - 13 = 0 ( add 13 to both sides )

x² + 3x = 13

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2( $\frac{3}{2}$ )x + ( $\frac{3}{2}$ )² = 13 + ( $\frac{3}{2}$ )², that is

x² + 2( $\frac{3}{2}$ )x + $\frac{9}{4}$ = 13 + $\frac{9}{4}$

(x + $\frac{3}{2}$ )² = $\frac{61}{4}$

The required number to be added to complete the square is $\frac{9}{4}$

In order to answer this U have to look at the table... this isn't even asking a question... so find the table and the question and it'll probably be easier to answer
