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.
