Hey there

Answer:

- 1976

Explanation:

${5x}^(2) - 5x - 169 = {2x}^(2) + x + 5 \\ \\ {5x}^(2) - 5x - 169 - {2x}^(2) - x + 5 = 0 \\ \\ {3x}^(2) - 4x - 164 = 0$

Therefore, finding the discriminant:

a = 3 b = -4 c = 164

We, know that to find discriminant.

b^2 - 4.a.c

(-4)^2-4.3.164

-8 - 1968

- 1976

Hope it help you
