p(x) = x²+3x+2
p(x) = x²+2x+x+2
p(x) = x(x+2)+1(x+2)
p(x) = (x+1)(x+2)
done.
p(x) = x²+2x+x+2
p(x) = x(x+2)+1(x+2)
p(x) = (x+1)(x+2)
done.

Hey dear!!
Here is yr answer
_____________________________
Method l :
~~~~~~~~~
=> x² + 3x + 2
Use middle splitting method.... for the above quadratic equation!
=> x² + 2x + 1x + 2
=> x (x+2) + 1 (x+2)
=> (x+2) (x+1)
x = -2 or x = -1
Method ll :
~~~~~~~~~
=> x² + 3x + 2
=> x² + (2+1)x + 2×1
It is in the form of ----
[ x² + (a+b)x + ab = (x+a) (x+b) ]
x = x, a = 2 , b = 1
=> (x+2) (x+1)
x = -2 or x = -1
Hope it hlpz....
