Please, use "^" to denote exponentiation:  x^2, not x2.

f(x) = x^2 + 5x – 6 becomes g(x) if we replace each x in f(x) with (x+4):

g(x) = (x+4)^2 + 5(x+4) - 6

This can be expanded:  g(x) = x^2 + 8x + 16 + 5x + 20 - 6, or
                                       g(x) = x^2 + 13x + 30

Answer:

g(x)=(x+4)^2+5(x+4)-6
