Answer:
Explanation:
The quadratic formula is as follows:
![(-b+/-√(b^2-4ac) )/(2a)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/iakdcqkecfb0y65nozci8c63c4mbkhtnnn.png)
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:
![y=ax^2+bx+c](https://img.qammunity.org/2020/formulas/mathematics/middle-school/681jf4lsjwxd9lmjd27bh82m6tps71a0gl.png)
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.
