Question

hero · Answer

Drop the parentheses, then add like terms

anonymous · Answer

I don't know how...

xishem · Answer

$$(5x^2+3x-4)+(3x^2-x+2)$$$$5x^2+3x-4+3x^2-x+2$$$$8x^2+2x-2$$

anonymous · Answer

8x^2+2x-2

anonymous · Answer

Adding like terms means adding the exponents together, the whole numbers together...

precal · Answer

or distribute 1 and then combine like terms

precal · Answer

adding like terms is not adding the exponents together

anonymous · Answer

Oh that sounded screwed...
Add the whole #s with exponents... Right?

anonymous · Answer

Ok, now how do I do this one (2e^2-5e0+(7e-3e^20)?

precal · Answer

2x+3x = 5x
2x^2 + 3x  you can not combine because 2x has the 2nd power and 3x has the 1st power  (not like terms)

It's hard to type w/ a broken finger, but that's what you're trying to get at..

precal · Answer

I know especially when this is slow....
