Question 217742
The  basic  form  of  quadratic  equations  is,,,,
.
ax^2 +bx +c = 0
.
The  easiest  method  of  solution  for  x  is  to  factor,  and  set  factors  = 0
.
some  eqns  are  just  hard  to  factor,,,,for  those  use  the  general  "quadratic  formula",,,
.
x= { -b +/- sqrt{b^2 -4ac} / 2*a
.
Note,  all  quadratic eqn  have  2  solutions,,,some  may  be  immaginary.
.
Good  luck
.
Practice  makes  perfect
