Which is the best description of the equivalency of the two expressions? Expression 1
5x? - 2x-4+6x+ 3
Expression 2
Bx² - 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.
