you can rewrite a as

right?

Answer 3

im not sure im totally wack at this topic

Answer 4

wait. sorry. 2a/2a is 1

Answer 5

\[a = \frac{2a^2}{2a}\]
that's better

Answer 6

so replace the a with 2a^2/2a to get \[\frac{2a^2}{2a} - \frac 3{2a}\]
do you follow?

Answer 7

uhm some what

Answer 8

so now you have common denominators. that means all that's left now is to subtract the numerators then copy the denominator. just like this \[\frac 32 - \frac 12 = \frac{3-1}2\]
got it?

Answer 9

ok so one thing I look for the lcd to get common denominator and thanks beautiful ;)
