Look for a common factor.
 
12x2+14x=0 has a common factor or 2x
 
2x(6x+7)=0
 
Or you can solve for x
 
12x2+14x = 0  can be rearranged to:
 
12x2=-14x 
 
divide both sides by 2x reduces to:
 
6x = -7
 
divide both sides by 6 gives:
 
x = -7/6 or -1.166......
 
Hope this is what your looking for.
 
 
12x2 + 14x=0
 
First, factor what both terms have in common.  (this should ALWAYS be your first step - if possible)
We can factor out a 2x
 
2x(6x+7)=0
 
Set both terms = 0
 
2x = 0     AND   6x+7=0
 
x=0                   x=-7/6
