Answer:
4(2x+3)
Step-by-step explanation:
8x+12
4(2x+3)
----------------
Note that 8x+12=4(2x+3),
because we factored out 4.
Sal's answer is wrong because even though 2(4x+6)=8x+12,
but the answer 4(2x+3) is more reasonable,
because our goal is to find the largest number when factoring an expression.
