If (x-2) is factor then it will be equals to zero.
Then x-2=0,
=> x=2
∴f(2)=2²+4*2+3=4+8+3=15
∵its coming 15
∴its not a factor.

NO
x²+4x+3
x²+3x+x+3
x(x+3)+1(x+3)
(x+3)(x+1)
so ,the factor of the sum is not (x-2)
since x²+4x+3=(x+3)(x+1)
x²+4x+3
x²+3x+x+3
x(x+3)+1(x+3)
(x+3)(x+1)
so ,the factor of the sum is not (x-2)
since x²+4x+3=(x+3)(x+1)
thank you
