    Drop the parentheses, then add like terms

    \[(5x^2+3x-4)+(3x^2-x+2)\]\[5x^2+3x-4+3x^2-x+2\]\[8x^2+2x-2\]

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

    or distribute 1 and then combine like terms

    adding like terms is not adding the exponents together

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

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

    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..
