Which model represents the factors of x2 9x 8? An algebra tile configuration. 7 tiles are in the Factor 1 spot: 1 is labeled x a
2 answers:
The factors of an expression are the quotients of the expression
The model that represents the factors of is the product of x -1 and x - 8
The expression is given as:
Expand the expression
Factorize the expression
Factor out x - 8
Hence, the model that represents the factors of is the product of x -1 and x - 8

Answer:
Radius of the convergence is R =
and,
The Interval of convergence is
Step-by-step explanation:
Given function : Σ(21x)^k
Now,
Using the ratio test, we have
R =
or
R =
or
R =
now,
for convergence R|x| < 1
Therefore,
< 1
or
and,
Radius of the convergence is R =
and,
The Interval of convergence is
