Hey there
Answer:
- 1976
Step-by-step explanation:
[tex] {5x}^{2} - 5x - 169 = {2x}^{2} + x + 5 \\ \\ {5x}^{2} - 5x - 169 - {2x}^{2} - x + 5 = 0 \\ \\ {3x}^{2} - 4x - 164 = 0[/tex]
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
