<h2>Hey there </h2>

<h2>Answer:</h2>

<h3>- 1976</h3>

<h2>Step-by-step explanation:</h2>

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

<h2>Therefore, finding the discriminant:</h2>

<h3>a = 3 b = -4 c = 164</h3>

<h3>We, know that to find discriminant. </h3>

<h3>b^2 - 4.a.c</h3>

<h3>(-4)^2-4.3.164</h3>

<h3>-8 - 1968</h3>

<h3>- 1976</h3>

<h2>Hope it help you</h2>
