If (4x + 7)(x + 2) = 8x^2 + x, what is a possible value of x?
Answers.
A) 12 B) -7 C) 7 D) -1 E) -14
Rearranging the given expression:   (4x + 7)(x + 2) = 8x^2 + x   i.e. 8x^2 + 15x + 14 = 8x^2 + x   i.e. 14x = -14   i.e. x = -14/14 = -1   Answer: Option -1   Had it been a difficult expression to solve further, then we could have used options to check which on esatisfies the expression after solving it as further as possible
