Question

show the steps to find the difference please.
 -5(x^2 + 2x – 5) – (7x^2 – 2x – 3)

anonymous · Answer

@myininaya the champ can you help

anonymous · Answer

Distribute the -5.... -5x^2 -10x +25 -7x^2 -2x-3   then put like terms together.... -12x^2 -12x +22

anonymous · Answer

then what?

anonymous · Answer

That is the difference between the two polynomials.

anonymous · Answer

2?

anonymous · Answer

-12x^2 -12x +22

anonymous · Answer

so thats the answer? -12x^2 - 12x + 22? if so then i was way off

anonymous · Answer

That is the answer.  You can't subtract the an x term from a x^2 term and you can't subtract the single numbers (22) from the x term or x^2 term unless they gave you a value for x or gave you a complete equation; as in x-2 =0  then you know x =2.  make sense?

anonymous · Answer

yes, I guess its go back to the beginning of the chapter and re-read .. thank you

anonymous · Answer

You're welcome.

myininaya · Answer

You guys need to distribute the negative one for the second grouping of terms
-(a-b-c)=-a+b+c

anonymous · Answer

That is true.  Good catch @myininaya
