Answer:
2(a*b)-a/b
Explanation:
So, read the problem and anlyze it.
To simplify what it says: The difference (subtraction), of twice the product(multiplacation) , and quotient of a & b.
So:
2(a*b)- a/b
Keep in mind that, they are not asking for twice of a/b. Only tice of the multiplacation part. They are asking the difference between both!
