Answer:

Explanation:

The quadratic formula is as follows:


(-b+/-√(b^2-4ac) )/(2a)

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

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.
