To simplify the expression "(3g-4)-2 (3g+4)", we can start by distributing the -2 to the terms inside the parentheses on the right side:
(3g-4)-2(3g+4)
= 3g-4-2(3g)-2(4)
Next, we can multiply the -2 by 3g and 4:
= 3g-4-6g-8
Now, we can combine like terms:
= (3g-6g) + (-4-8)
= -3g -12
Therefore, the simplified form of "(3g-4)-2 (3g+4)" is -3g -12.
(3g-4)-2 (3g+4)
