3x^2 +2x-1=0

3x^2 +2x-1=0

I am looking for 2 numbers that mult to 3*-1=-3   and add to +2

I see that the numbers are  -3 and +1

so now I will split 2x into  -3x+1x

$$\\3x^2 +2x-1=0\\ 3x^2-3x +1x-1=0\\ 3x(x-1) +1(x-1)\\ (3x+1)(x-1)=0$$

3x+1=0   or    x-1=0

3x=-1      or     x=1

x= -1/3    or     x=1
