To use the Quadratic Formula, the equation must be in the standard form of a quadratic equation, which is \( ax^2 + bx + c = 0 \). Therefore, in this case, you need to set the equation equal to zero.
The given equation is:
\[ 7x^2 + 2x = 4. \]
To set it equal to zero, you would subtract 4 from both sides, resulting in:
\[ 7x^2 + 2x - 4 = 0. \]
Thus, the correct action before identifying \( a \), \( b \), and \( c \) is:
• The equation needs to be set equal to zero.
