Answer 2

To evaluate the limit of the given expression as x approaches -1/2, we can simply substitute x = -1/2 into the expression and simplify.

lim x->(-1/2) (2x^2-7x-4)/(-2x^2+5x+3)

= (2(-1/2)^2 - 7(-1/2) - 4)/(-2(-1/2)^2 + 5(-1/2) + 3)

= (2(1/4) + 7/2 - 4)/(-2(1/4) - 5/2 + 3)

= (-1/4)/(1/4)

= -1

Therefore, the limit of the given expression as x approaches -1/2 is -1.
