Answer:
+ 1
Step-by-step explanation:
Given
x² + 2x = 9
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1² = 9 + 1²
(x + 1)² = 10
14 = 9 - p
Move 9 to the other side
Sign changes from +9 to -9
14-9= 9-9-p
14-9= -p
5=-p
Mutiply both sides by -1 to get + p
(5)(-1)= (-p)(-1)
p= -5
Answer: p= -5
