Simplify the expression:​

Answer 1

Answer: $19u^{2} -12u$

Step-by-step 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.

$19u^{2}-12u$
