Two sets of equatic expressions are shown below in various forms:
Line 1: x^2 + 3x + 2 (x + 1)(x + 2) (x + 1.5)^2 − 0.25
Line 2: x^2 + 5x + 6 (x + 2)(x + 3) (x + 2.5)^2 + 6.25
Which line contains three equivalent expressions?

Best ResponseYou've already chosen the best response.1Do you know how to distribute out the parenthesis? e.g) (x+1)(x+2)

Best ResponseYou've already chosen the best response.0I think so don't you use FOIL? @johnweldon1993

Best ResponseYou've already chosen the best response.1Yes use foil to distribute those out..in both cases

Best ResponseYou've already chosen the best response.0line 1 x^2 +2x+x+2 line 2 x^2+3x+2x+6 is that correct @johnweldon1993

Best ResponseYou've already chosen the best response.1yes...now just combine like terms...and we have line 1) x^2 + 3x + 2 line 2) x^2 + 5x + 6 So far those match the first part of each line...so we move onto the next part as well So now we need to distribute the line 1) (x + 1.5)^2  0.25 line 2) (x + 2.5)^2 + 6.25

Best ResponseYou've already chosen the best response.0then it would be x^2 +1.5^20.25 x^2+2.5^2+6.25

Best ResponseYou've already chosen the best response.1Ahh not quite :) So think of something like \[\large (x + a)^2 \rightarrow (x + a)(x + a)\]

Best ResponseYou've already chosen the best response.0oo so it would be (x+1.5)(x+1.5)0.25 (x+2.5)(x+2.5)+6.25 @johnweldon1993

Best ResponseYou've already chosen the best response.1Correct....so you foil those parenthesis out and then just simplify :)

Best ResponseYou've already chosen the best response.0the first one should be x^2+3x+2

Best ResponseYou've already chosen the best response.0the second one should be x^2+5x+12.5

Best ResponseYou've already chosen the best response.1Perfect....so as you can see...line 1 is the same...but line 2 is no longer the same..thus the answer is...?
