2 answers:
Answer:
x^2 - x + 1/4
Step-by-step explanation:
To complete the square
x^2 - x + P
Take the coefficient of x
-1
Divide by 2
-1/2
Then square it
(-1/2)^2
1/4
Add this to complete the square
x^2 - x + 1/4
Answer:
p = 
Step-by-step explanation:
To make a perfect square
add ( half the coefficient of the x- term )² to x² - x, that is
x² + 2(-
)x +
with p =
, thus
x² - x = (x -
)² +

Answer:
8.4 in by 8.4 in
Step-by-step explanation:
The area of a square is the side length squared.
Let s be the side length:
s^2 = 70
s = \sqrt(70) = 8.4 in
6.299 or 6.3 depending on how it wants you to round
