7 1/2 is to the left of 17 2/3 on a number line because 7 1/2 is less then 17 2/3
Answer:
or
is a factor of the given polynomial.
Step-by-step explanation:
Let us learn the concept with an example first.
Let the polynomial be a quadratic function
.

The roots of
are 2 and 3.
Putting 
Putting 

Putting x = 2 or x = 3, g(x) = 0
The roots of equation g(x) are 2 and 3.
Now, let us try to factorize g(x):

so, the equation can be written as:
where 3 and 2 are the roots of equation.
The factors are (x-3) and (x-2).
for the polynomial f(x) which has roots
will have a factor:
or 
Answer: -9
Step-by-step explanation:
(2-8) times (-3-9) divided by -8
(-6 times -12) divided by -8
72 divided by -8
-9
It can be simplified more: ab^11
