Which is the best description of the equivalency of the two expressions? Expression 1
5x? - 2x-4+6x+ 3
Expression 2
6x² - 6x+6-x?+ 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 x? 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
