### Completing The Square

## Learning Goals:

-How and Where each variable goes in the x equation

-Solve word equations Using the x equation

-Convert Vertex equations into standard form

## Summary

## Quadratic Formula Example

## Completing the Square Example

Likewise as the 1st example completing the square involves the formula x= -b +- (square root) b^2 - 4(a)(c) divided by 2 (a).Once this is done the last part of the equation will be x = -b + (square root of the product) divided by product of a and 2. That and another one only positive instead of a negative. The reason you get two answers is because in a parabola there is a high chance of having two x intercepts. There can also be one x intercept or no x intercept(s).
