which of the following correctly shows the quadratic formula?

Answer:
A) x = [tex]\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}[/tex]
Step-by-step explanation:
The general form a quadratic equation y = [tex]ax^2 + bx + c, where a \neq 0.[/tex].
We use quadratic formula when we find the solution of a quadratic equation.
The quadratic equation has two solutions.
x = [tex]\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}[/tex]
Therefore, the answer is A) x = [tex]\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}[/tex]
