Given:


4x^2-5=3x+4

To find:

The correct setup for solving the equation using the quadratic formula.​

Step-by-step explanation:

It can be simplified as,


\begin{gathered} 4x^2-5-3x-4=0 \\ 4x^2-3x-9=0 \end{gathered}

Here,


\begin{gathered} a=4 \\ b=-3 \\ c=-9 \end{gathered}

Using the quadratic formula,


x=(-b\pm√(b^2-4ac))/(2a)

Plugging in the values, we get


x=(-(-3)\pm√((-3)^2-4(4)(-9)))/(2(4))

Final answer:

The correct choice is D.
