%28red%288x%5E2%29+%2B+green%285x%29-3%29%2B+%28red%2812x%5E2%29+%2Bgreen%287x%29-14%29

Combine the red terms getting red%288x%5E2%2B12x%5E2=20x%5E2%29

Combine the green terms gettinggreen%285x%2B7x=12x%29

Combine the black terms getting -3-14=-17

So the answer is 20x%5E2%2B12x-17

Use the caret mark, "^" (Shift-6) to indicate raising to a power. I'm presuming you meant:



which can be rendered using a standard keyboard by:

(8x^2 + 5x - 3) + (12x^2 + 7x - 14)

Enough housekeeping, let's do the math.

First get rid of the parentheses. In front of the first set of parentheses there is an understood coefficient of 1. Multiplying anything by 1 doesn't change anything, so just drop the parentheses altogether. In this case you also have an understood coefficient of 1 in front of the second set of parentheses -- they go away too:



Terms are the chunks that are separated by + and - signs. You can combine like terms. Like terms have the same variable(s) raised to the same power(s). The and the are like terms because exactly matches . Sort of like saying I have 8 bananas and 12 bananas so I have 20 bananas. (but you can't add in the term because that would be adding in the apples while you are counting bananas) So we have . Likewise, add up the terms that have in them, namely and . And finally add up the terms that are just constant coefficients, the and the .

All together you should have:
