SOLUTION: perform the indicated operation 5/3a - 9 - 3/2a + 4/a^2 -3a Is this where you find the LCD and then go from there? 3= 3 9 = 3^3 2= 2 largest ones = 3^3 * 3 * 2 =

Question 7943: perform the indicated operation

5/3a - 9 - 3/2a + 4/a^2 -3a

Is this where you find the LCD and then go from there?
3= 3
9 = 3^3
2= 2
largest DISABLED_event_ones= 3^3 * 3 * 2 = 54a^2

Book answer is: a + 51/ 6a(a-3)
Pleae help. Thanks to all

you have to write it down correctly on here, anywhere even: maths is a language and if you speak it incorrectly, then others will mis-interpret you: To get the answer you quoted, you need

To alter any fraction, beit a numerical or algebraic fraction, you need to scale it up. We do this by multiplying by "1", to keep the actual fraction unchanged, but we write 1 as something like a/a...

Right then, looking at all the denominators, we need to get them all the same: the LCM is 6a(a-3)...so

first term is multiplied by
second term is multiplied by
third term is multiplied by

so we then get:
