Answer:
x^2+16x+64=(x+8)^2
Step-by-step explanation:
For the first spot you find the perfect square of the equation
This is found by doing (1/2 16)^2
1/2 16 = 8
8^2 = 64
The second spot is factoring, where you would put half of 16 or the square root of 64
1/2 16 = 8
root 64 = 8
Ax + by = c
Ax + by (- Ax) = c (-Ax)
by = c - Ax
by/b = (c - Ax)/b
y = (c - Ax)/b
hope this helps :D
