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
