Hi there!

x² + 3x + 2
We know that x + 1 is a factor, so:
We must find another number that adds up to 3 when added to 1 and multiplies into 2 with 1. We get:
x + 2
(x + 1)(x + 2)
3n - 4n - 2
-n - 2
-n - 2 is the simplest form
So 3/4 of 12
remember that 12=12/1
and if you ahve x/y times z/t that equals to (xz)/(yt) so
'of' means multiply
3/4 times 12/1=(3 times 12)/(4 times 1)=36/4=9/1=9
