One is a linear and the other is a quadratic polynomial.
And (x+2) is indeed a factor.
You can rewrite it as (x+2)(3x-7)
Answer:
x = 2
Step-by-step explanation:
2 to the second power is 4. 4 subtracted by 4 is zero.
Answer:
15 days
Step-by-step explanation:
Let x be the number of days needed for B to complete the job. Then x-5 is the number of days needed for A to complete the job.
In 1 day,
- A completes
of all work; - B completes
of all work.
Hence, in 1 day both A and B complete 
of all work. A and B working together can do a work in 6 days. Then
Solve this equation:
If 
then 
that is impossible. So, B needs 15 days to complete the work alone.
Answer:
The answer is (5,-6)
Step-by-step explanation:
it's the only point that's both on the line and and further away from point A
