you can use ^ to show exponents 14+2x^2 3x + 5x^2 + 66x better use the equation editor \[ 14+2x^2 3x + 5x^2 + 66x \]

phi Group TitleBest ResponseYou've already chosen the best response.1
when adding you can change the order so you could write it like this \[ 5x^2 + 2x^2 3x6x14+6 \]

phi Group TitleBest ResponseYou've already chosen the best response.1
it should be clear what 14+6 is for the x^2 terms: if you have 5 x^2 terms and add 2 more x^2 terms, how many x^2 terms do you have ?

2 x's because 3x and 6x right
 one year ago

phi Group TitleBest ResponseYou've already chosen the best response.1
it is 3x 6x we could "factor out" the x to get (36) x now what is 36 ?

is the 6 a negative too
 one year ago

lvasquev462 Group TitleBest ResponseYou've already chosen the best response.0
if the six is negative it be 9 right
 one year ago

phi Group TitleBest ResponseYou've already chosen the best response.1
yes 36 is 9 so the answer is 9x the whole answer is \[ 7x^2 9x8 \] if negative numbers are unclear, see http://www.khanacademy.org/math/arithmetic/absolutevalue/adding_subtracting_negatives/v/negativenumbersintroduction
