Two sets of equatic expressions are shown below in various forms:
Line 1: x2 + 3x + 2 (x + 1)(x + 2) (x + 1.5)2 − 0.25
Line 2: x2 + 5x + 6 (x + 2)(x + 3) (x + 2.5)2 + 6.25
Which line contains three equivalent expressions?
Line 1 only
Line 2 only
Both Line 1 and Line 2
Neither Line 1 nor Line 2

Best ResponseYou've already chosen the best response.1(x + 1)(x+ 2) = x^2 + 2x + x + 2 = x^2 + 3x + 2 that one matches

Best ResponseYou've already chosen the best response.1(x+1.5)^2  0.25 = x^2 + 1.5x + 1.5x + 2.25  0.25 = x^2 + 3x + 2 That one is also the same, so line 1 is all same

Best ResponseYou've already chosen the best response.1\[(x+2.5)^2 + 6.5 = x^2+2.5x+2.5x+6.25 + 6.25\]
