Respuesta :

X equals negative B and plus and minus the square root of b squared minus 4ac all over 2a

Answer:

Step-by-step explanation:

The quadratic formula is as follows:

[tex]\frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]

It is used for factoring second degree polynomials ONLY!!!  That's why it's called the quadratic formula...quadratics are second degree polynomials.  The a, b and c are found in the standard form of a quadratic equation:

[tex]y=ax^2+bx+c[/tex]

Just plug them into the formula, but be careful with the "-4ac".  Sometimes that mistakenly leads to an unwanted negative sign under you radical.  Unless you are dealing with imaginary numbers, your solutions should be real.
