<h3>
Answer: 2x+21</h3>
=============================
Work Shown:
f(x) - g(x) = [ f(x) ] - [ g(x) ]
f(x) - g(x) = [ 7x+15 ] - [ 5x-6 ]
f(x) - g(x) = 7x+15 - 5x+6
f(x) - g(x) = (7x-5x)+(15+6)
f(x) - g(x) = 2x+21

Answer:
The answer is option A. 2x - 3
The expression 3x - 4 is subtracted from
5x - 7 is written as
5x - 7 - (3x - 4)
= 5x - 7 - 3x + 4
= 2x - 7 + 4
= 2x - 3
Hope this helps
OK.
-- Since it's the difference of two squares,
the factored form of that expression is
(5x + 12) (5x - 12) .
-- We don't know the value of the expression
until you tell us the value of 'x'. And then, if
'x' changes, the value of the expression also
changes, immediately, without any delay.
