Question:

Expanding from what was learned in Algebra 1, what is the quadratic formula and for what purpose is it used?

Taylor N.
Answer:

The Quadratic formula is x equals the quantity of negative b plus or minus the square root of the quantity b squared minus 4ac, all over the quantity of 2a. Or x = (-b ± √(b^2-4ac)) / (2a). It is used to find the simplified version, or the zeros, of the equation y = ax^2 + bx + c.
