But be careful if you have a subtract instead of add

Answer 5

okay

Answer 6

so what about \[(2x ^{2}-3x+4)-(x ^{2}+4x-1)\] ?

Answer 7

\[2x^{2}-3x+4-x^{2}-4x+1\]
\[2x^{2}-x^{2}-3x-4x+4+1\]
\[x^{2}-7x+5\]

Answer 8

oh okay i get it thanks :)

Answer 9

can \[(-4x ^{2})(2x)\] be simplified?

Answer 10

No problem just always remember to get rid of the brackets first
Get rid isn't the right terminology but you know what I mean
Eg time sing by minus one to get rid of the negative sign
Then gather like terms then rewrite it :)

Answer 11

It could be written as \[-8x^{3}\] which is simpler
