Have you considered adding the "like" terms?

popitree · Answer

add the like terms square with square like that
then factorize

anonymous · Answer

why cant ijust give them the answer

butterflyhope · Answer

Yes, but i'm not very good at it ;-;

I thought the answer was -6x^3 + 20x^3.

anonymous · Answer

lol thats wrong

anonymous · Answer

$$(3x^2 + 5x - 14) + (5x^2 + 4x + 11)$$
$$=3x^2+5x^2+5x+4x-14+11$$ has the like terms next to each other

butterflyhope · Answer

I know @jetfreak3

anonymous · Answer

then since $3+5=8$ you have 
$$3x^2+5x^2=8x^2$$

anonymous · Answer

just like 3 dollars and 5 dollars is 8 dollars, so $3x^2+5x^2=8x^2$

anonymous · Answer

also $5x+4x=9x$ for the same reason

anonymous · Answer

finally $-14+11=-3$

tkhunny · Answer

@jetfreak3 You cannot just give the answer because that would be wrong.
