PLS HELP ! Will give brainliest

Darina [25.2K]

Answer:

Step-by-step explanation:

The quadratic formula would be the following...

$x = \frac{-b (+-)\sqrt{b^{2} - 4ac } }{2a}$

where the original quadratic equation would be represented as follows

$ax^{2} + bx +c = 0$

Using this information and the information provided in the image we can plug in the quadratic equation values in the image to form the quadratic formula.

$\frac{-(-20)±\sqrt{(-20)^{2} - 4(16)(-6) } }{2(16)}$

That would be the correct order for the values.
