Best ResponseYou've already chosen the best response.1I think it is B because it would end up being a^2abba+b^2 Unless there is a zero of course so then it could be A

Best ResponseYou've already chosen the best response.0Find the two products below. Compare and contrast, in complete sentences, the similarities and differences of the two. (x + 4)(x − 4) and (x + 4)(x + 4)

Best ResponseYou've already chosen the best response.1the first would play out to x^24x+4x16 leaving you with x^216 The second would become x^2+4x+4x+14 leaving you with x^2+8x+14 See the difference?

Best ResponseYou've already chosen the best response.1So the second is +16 not +14

Best ResponseYou've already chosen the best response.1the first x multiplies to each term in the second set of parenthesis. Then the first 4 multiplies to each term in the second set of parenthesis. Add all the terms together and you are good to go :)

Best ResponseYou've already chosen the best response.0(x + 4)(x + 4) x^2 + 4 + 4 + 16 this is what i get for the second equation

Best ResponseYou've already chosen the best response.1Yes but remember to carry x along. The second and third terms you have just 4. But the 4 multiplies with x making them each 4x So x^2+4x+4x+16

Best ResponseYou've already chosen the best response.1You will be expected to combine like terms as well. So go ahead and add the 4xs together giving you 8x making your final result for that problem x^2+8x+16

Best ResponseYou've already chosen the best response.0oh okay can you help me out with the similarities and differences of the two equations?

Best ResponseYou've already chosen the best response.1You can see from our calculations that it is the minus sign that causes the major differences. It turns positive 16 into negative 16 and instead of creating 8x with the 4xs, the 4xs end up canceling each other out because 11=0 so 4x4x=0 as well.

Best ResponseYou've already chosen the best response.1Notice though that both problems do yield an x^2 and a 16(just a negative 16 for one of them)
