If using the method of completing the square to solve the quadratic equation x^2+3x-13=0x 2 +3x−13=0, which number would have to be added to "complete the square"?

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( )x + ( )² = 13 + ( )², that is

x² + 2( )x + = 13 +

(x + )² =

The required number to be added to complete the square is

i’m sorry but i don’t know sorry
