Before using the Quadratic Formula to solve the equation \(7x^2 + 2x = 4\), you need to set the equation equal to zero. This involves rearranging the equation so that one side equals zero.
To do this, you would subtract 4 from both sides:
\[7x^2 + 2x - 4 = 0\]
Once this is done, you can identify the coefficients \(a\), \(b\), and \(c\).
So, the correct response is:
**The equation needs to be set equal to zero.**
