Given the equation:

[tex]\text{ x}^2\text{ + 3x - 4 = 0}[/tex]

To find x, since the equation is in the standard form of Quadratic Equation, we will be using the Quadratic formula:

[tex]\text{ x =}\frac{-b\text{ }\pm\text{ }\sqrt[]{b^2-4ac}}{2a}[/tex]

At,

[tex]ax^2\text{ + bx + c = 0}[/tex]

Where,

a = coefficient at = 1

b = coefficient at x = 3

c = constant = -4

Let's plug in the values to find for x:

[tex]\text{ x =}\frac{-b\text{ }\pm\text{ }\sqrt[]{b^2-4ac}}{2a}[/tex][tex]undefined[/tex]
