Question

You are solving a quadratic by using the Quadratic Formula, what needs to be done to this function before we can identify a, b, and c? 7x^2 + 2x = 4
A) The equation needs to be set equal to zero.
B) The like terms need to be combined.
C) We need to add 4 on both sides of the equation.
D) The quadratic first needs to be factored.

To apply the Quadratic Formula, the equation needs to be in the standard form of a quadratic equation, which is \( ax^2 + bx + c = 0 \). In this case, you start with the equation:

\[ 7x^2 + 2x = 4 \]

To get it into the correct form, you need to move all the terms to one side so that the equation is equal to zero. This means you subtract 4 from both sides:

\[ 7x^2 + 2x - 4 = 0 \]

Thus, the necessary step before identifying \( a \), \( b \), and \( c \) is:

**A) The equation needs to be set equal to zero.**
