How can I simplify this expression
kodGreya [7K]
Usually, "simplify" means to remove any common factors and express the sum as a single fraction, often in multiplie-out form.

If you factor what you've got, you will write it as
\dfrac{(m+2)(m-2)}{(m+1)}+\dfrac{(m+2)}{(m+1)^2}=\dfrac{m+2}{m+1}\cdot\left((m-2)+\dfrac{1}{m+1}\right)\\\\=\dfrac{m+2}{m+1}\cdot\dfrac{(m-2)(m+1)+1}{m+1}\\\\=\dfrac{(m+2)(m^2-m-1)}{(m+1)^2}\\\\=\dfrac{m^3+m^2-3m-2}{m^2+2m+1}

andreev551 [17]

Answer:

job A

Step-by-step explanation:

job B pays $34560 yearly because every since it pays $720 weekly and there are 48 weeks in a year $720 multiplied by 48 is $34560. Job C pays $37440 because there are 12 months in a year and semimonthly means two times per month so 12 times 2 times $1560 give you $37440. Therefore job A pays the most amount per year.
