What brought me here is my confusion across this math problem I've encountered. Here's the problem; Code: 4y^2+32y+48 What I've done was. Code: 4(y^2+32y+48) > 4( y + ) ( y + ) this is where I'm clueless.

When you factor out the 4, you must divide all of the terms by 4, to get: $4y^2+32y+48=4$$y^2+8y+12$$$ Now, to factor the quadratic within the parentheses, you need two factors of 12 whose sum is 8, which is 2 and 6, so we then get: $4(y+6)(y+2)$
