Question

Simplify the expression:
​

Answer 1

Answer:
`19u^(2) -12u`

Explanation:

1) You would have to distubite the 2 to the numbers inside the paretheis.

`( -12u + 20u^(2) ) + -u^(2)`

2) After that you add the like terms together.

`20u^(2)-u^(2)= 19u^(2)`

`-12u` (Nothing to add this term with.)

3) Put them together to make your answer.

`19u^(2)-12u`
