Best ResponseYou've already chosen the best response.1\[(3x ^{2}+2x +7x ^{3})+(10x ^{2}+6x +9)\] This needs simplified and I'm not sure whre to begin.

Best ResponseYou've already chosen the best response.2First step is to remove the brackets. Next gather like terms.

Best ResponseYou've already chosen the best response.1What do you mean by remove the brackets? And when I combine the like terms, do I add the add the exponents?

Best ResponseYou've already chosen the best response.2Removing the brackets gives \[\large 3x^{2}+2x+7x^{3}+10x^{2}+6x+9\] The terms in xsquared are like terms. To add the 2 terms in xsquared, just add the coefficients of xsquared (3 + 10 = 13).

Best ResponseYou've already chosen the best response.1Oh, ok. So I have \[13x ^{2}+2x +7x ^{3}+6x +9\]

Best ResponseYou've already chosen the best response.1can I combine 2x and 6x?

Best ResponseYou've already chosen the best response.2The terms in x are also like terms. To add them just add the coefficients (2 + 6 = 8).

Best ResponseYou've already chosen the best response.1Right. SO now: \[13x ^{2}+8x+7x ^{3}+9\] And so is that it?

Best ResponseYou've already chosen the best response.0The next step is to arrange in decreasing order of powers, not really necessary but yeah.. \[7x^3+13x^2+8x+9\] Looks more nice that way

Best ResponseYou've already chosen the best response.2Nearly finished. The last step is to arrange the terms in descending powers of x, starting with x cubed.
