3x^2 + 4x + 1

= 3x^2 + 3x + (x+1)

= 3x(x+1) + (x+1)

= (x+1)(3x+1)

....

x^2 + x

= x(x+1)

so

f(x)

= (x+1)(3x+1) / (x(x+1)

= (3x + 1)/x

will leave the rest to you.....

3x^2 + 4x + 1 = (3x + 1)(x + 1)

x^2 + x = x(x + 1)

So the expression simplifies to (3x + 1) / x

You can take it from here!
