(The second of three ways to solve (find the roots) of quadratics)

`x=(-b+-sqrt(b^2-4ac))/(2a)`

 

The negative boy story

The negative boy story and how he missed the party can help you remember each part of the quadratic formula

A negative boy (`-b`  ) couldn't decide (`+-`  ) whether to go to a radical party (`sqrt` ) but being square (`b^2` ) he decided not to go (`-` ). He missed out on four (`4` ) amazing (`a` ) chicks (`c` ). The party was not over (  ______  ) until 2am (`2a` ).

 

Given any quadratic equation   `ax^2+bx+c=0`

we can substitute the values of `a` , `b` , & `c`  into the following formula and solve

`x=(-b+-sqrt(b^2-4ac))/(2a)`
