Answer:external factor
Step-by-step explanation:
For this case we have the following expression:
(x + 7) / (x ^ 2 - x - 2) = A / (x - 2) + B / (x + 1)
Rewriting we have:
(x + 7) / ((x-2) (x + 1)) = A / (x - 2) + B / (x + 1)
We multiply the equality by (x-2) (x + 1):
x + 7 = A (x + 1) + B (x - 2)
Rewriting we have the following system of equations:
A + B = 1
A - 2B = 7
Solving the system we have:
A = 3
B = -2
Answer:
constants A and B are:
A = 3
B = -2
A^2 + b^2 = c^2
In this case we are missing b, so
b= square root (c^2-a^2)
b= square root (13^2 -12^2)
b= 5 m
the answer is 7+5x because when you inverse something you reverse it.
