<h2>Using the quadratic formula</h2>

The quadratic formula can help us solve for x in a quadratic equation:

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

We can use this when the given equation is organized in standard form: ax^2+bx+c=0

<h3>Applying this to the problem</h3>

2x^2+5x-4=0

First we can identify the values of a, b and c:

a = 2

b = 5

c = -4

Plug these values into the quadratic formula:

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

x=\dfrac{-5 \pm \sqrt{5^2-4(2)(-4)}}{2(2)}

x=\dfrac{-5 \pm \sqrt{25+32}}{4}

x=\dfrac{-5 \pm \sqrt{57}}{4}

<h2>Answer</h2>

Therefore, the two possible values of x are:

x=\dfrac{-5 +\sqrt{57}}{4}

x=\dfrac{-5 -\sqrt{57}}{4}
