Question

add express your answer in simplest form

4/s+6/s^2

I think it is 4s+6/s^2 is this right?

Answer 1

4/s +6/s^2
=(4s+6)/s^2
=2(s+3)/s^2
so you are perfectly right in your calculation

Answer 2

First, find the LCD-least common denominator; which is s^2.

Factoring 2, you get a final answer of 2(2s+3)/s^2.

Your answer just needs Parentheses to be clearer and factoring 2 out. Parentheses are very important in Math. Use it liberally. It is not going to hurt. Your teacher will also appreciate it because your answers will be easier to correct.

Answer 3

4s^-1 + 6s^-2
when you take 's' from the bottom to the top it becomes s^-1, similarly s^2 becomes s^-2 ...
