Question

Simplify (13/5a^2 + (7/9)a - 5a +(10/9)a

Answer 1

The answer is -28/5a

Answer 2

So the answer is
`-(28)/(9)a`

Explanation:

`(13)/(5) a^2 + (7)/(9)a - 5a +\frac {10}{9}a`

Take like terms

`(7)/(9)a-5a+(10)/(9)a`

Turn the whole number into an improper fraction that has the same denominator as the other terms

`(5)/(1)a`⇒
`(45)/(9)a`

Subtract the second term from the first

`(7)/(9)a-(45)/(9)a=-(38)/(9)a`

Then add the last term

`-(38)/(9)a+(10)/(9)a=-(28)/(9)a`
