What is the numerical part of the divisor in the quadratic formula?

In the quadratic formula, which is used to find the solutions of a quadratic equation written in the standard form ( ax^2 + bx + c = 0 ), the expression is given by:

[

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

]

Focusing on the denominator, which is the divisor in the quadratic formula, it is represented by ( 2a ). The term "numerical part of the divisor" refers specifically to the coefficient of ( a ) within this expression.

In this case, the numerical part is ( 2 ) because it multiplies ( a ). Therefore, when analyzing the options given, the choice indicating the numerical part of the divisor is indeed ( 2 ). This understanding is vital for correctly applying the formula in solving quadratic equations.
