Help would be nice :p *pls don't leave this qestion.....I will cry :|*
Which is the best description of the equivalency of the two expressions?
Expression 1
5 x squared minus 2 x minus 4 + 6 x + 3
Expression 2
6 x squared minus 6 x + 6 minus x squared + 10 x minus 7
A.) The two expressions are not equivalent because when x = 2, the two expressions do not have the same value.
b.)The two expressions are not equivalent because when they are simplified, they do not have the same coefficients for the x squared and x terms.
c.) They are equivalent because the sum of the constants is the same in both expressions.
D.) They are equivalent because when x = 2, the two expressions have the same value.
