Question 951644
How does this work, what is this called?
If I have a problem like: {{{ 2x^2+5x-3=0 }}} for some reason it was brought to me I can break up the 5x like so {{{ 2x^2+6x-1x-3=0 }} and this makes it easier to factor like {{{ 2x(x+3) - (x+3) = 0 }}} and thus x=1/2 and x=-3. 
==========================
It's called quadratic equation, and equation of degree 2.
The object is to solve for x.  (Sometimes it's y or z, or some other variable.)

There's more than 1 way to do that, but the quadratic equation always works.
