----------------------------------------
I am stuck, can someone please assist me in understanding this type of problem?

Let f(x)- 4x^2-7x+3.  Find x such that f(x)=0.
------------------------------------------



You mean,  f(x)=4x^2-7x+3, and want x for f(x)=0 ?


{{{4x^2-7x+3=0}}}


Either factorize, if possible,  or use general solution formula.</PRE>
