To use the Quadratic Formula, the equation needs to be set equal to zero.
So the correct response is:
**The equation needs to be set equal to zero.**
You would do this by subtracting 4 from both sides of the equation, resulting in:
\[ 7x^2 + 2x - 4 = 0 \]
After this, you can identify \( a \), \( b \), and \( c \) for the quadratic formula.
