<u>Answer:</u>

x = 2.68, x = -0.186

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

We are given the following equation that we are to solve:

$2 x ^ 2 - 1 = 5 x$

Rearranging this quadratic equation to get:

$2 x ^ 2 -5 x - 1 = 0$

Solving it by using the quadratic formula as we cannot find any factors for it.

$x= \frac{-b \pm \sqrt{b^2-4ac} }{2a}$

$x=\frac{-(-5) \pm (-5)^2-4(2)(-1)}{2(2)}$

$x=\frac{5 \pm\sqrt{25+8} }{4}$

$x=\frac{5+\sqrt{33} }{4}$ , $x=\frac{5-\sqrt{33} }{4}$

x = 2.68, x = -0.186
