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