Answer:

see explanation

Step-by-step explanation:

To complete the square

add ( half the coefficient of the x- term )²

x² + 14x

= x² + 2(7)x + 49

= (x + 7)²

----------------------------------------

x² - 8x

= x² + 2(- 4)x + 16

= (x - 4)²

-----------------------------------------

x² + 5x

= x² + 2([tex]\frac{5}{2}[/tex] )x + [tex]\frac{25}{4}[/tex]

= (x + [tex]\frac{5}{2}[/tex] )²
