Which is the best description of the equivalency of the two expressions?
Expression 1
Expression 2
5x²-2x-4+6x+3
6x²-6x+6-x²+10x-7
The two expressions are not equivalent because when x=2, the two expressions do not have the same value.
The two expressions are not equivalent because when they are simplified, they do not have the same coefficients for
the x² and x terms.
They are equivalent because the sum of the constants is the same in both expressions.
They are equivalent because when x= 2, the two expressions have the same value.
