Two sets of quadratic equations are shown below in various forms.

Line 1: x2 − x − 6 (x + 2)(x − 3) (x + 0.5)2 − 6.25
Line 2: x2 − x − 2 (x + 1)(x − 2) (x − 0.5)2 − 2.25

Which line contains three equivalent expressions?

Line 1 only

Line 2 only

Both Line 1 and Line 2

Neither Line 1 nor Line 2

looking at line 1, lets FOIL the second equation to see if it looks like the first:
|dw:1384545090765:dw|

looking at the third equation, let's distribute the 2 to see if this equation is the same as the first:
|dw:1384545169842:dw|
