4x+2=3x need dont know what to do on this

 4x+2=3x
-4x     -4x
      2=-1x
    /-1=/-1
     -2=x
    

You need to subtract the 4x from both sides of the equation. so then you're left with 2=-1x because you subtracted 4 from 3 you have a negative 1. so after you've done that and you have the 2=-1x you need to divide both sides by -1. so divide 2 and -1  by -1. so it should look like this     2 = -1x

                                                                                        -1      -1 
picture is a little messed up but hopefully you get it.  Anyway after dividing the -1 cancels out so you're left with x= -2 
                               do you understand if not its okay to ask again. i know ths answer is all over the place!
                                                                                        
                                                                                

Aquadratic function is one of the form f(x)=ax2 + bx + c l, where a,b, and c are numbers with are not equal to zero.
