The roots of the equation 2x^2 - 5x - 4 = 2x + 3 can be written in the form x = (m±sqrt n)/p, where m, n, and p are positive integers with a greatest common divisor of 1. What is the value of n?

$2x^2 - 5x - 4 = 2x + 3$

$2x^2 - 7x - 7 = 0$

Discriminant = $(-7)^2 - 4(2)(-7) = 49 - (-56) = \boxed{105}$
