A and b together can do a piece of work in 8 days. If a alone can do the same work in 12 days, then b alone can do the same work
Nostrana [21]

B can finish the job alone in 24 days.

In work-rate problems, a certain person can complete a fraction of the job for a specific timeframe. As stated in the problem, A and B can finish the job by working together for 8 days. It must be noted that the fraction of the job they can finish individually per day is additive.

\frac{1}{A} + \frac{1}{B} = \frac{1}{8}

A can complete the work in 12 days and finish 1/12 fraction of a job per day. This can be substituted directly to the equation to solve for the time B needed to finish the work.

\frac{1}{12} + \frac{1}{B} = \frac{1}{8}

\frac{1}{B}= \frac{1}{8}- \frac{1}{12}

\frac{1}{B} = \frac{1}{24}

This means that B can do 1/24 fraction of the job per day and can completely finish the job in 24 days.

Can you solve this for me by: 
Slav-nsk [51]
2a^2-32

2*a^2-2*16

2*(a^2-16)

but we have a Difference of two square

x^2-y^2=(x+y)*(x-y)

now you can see it very well

2*(a^2-4^2)

so

\boxed{\boxed{2*(a-4)*(a+4)}}
