that's because the number before the brackets u time it by the number/s in the brackets and that gives the answer if you want a farther explanation message me
Explanation: To expand 3(4x+2), we need to distribute. This means that we need to multiply the numbers on the outside of the parentheses with the numbers on the inside of the parentheses. In this case, we need to multiply 3 times 4x and 3 times 2. Let’s do so now.
3(4x+2) 12x+6
This is your answer! When expanded, 3(4x+2) becomes 12x+6.
