Question

find the lcm and hcf in each case

1)x²+3x+2,x²-4
2)x⁴-27a³x,(x-3a)²

Answer 1

1 .x^2-2
is the answer is correct or not

Answer 2

For the first one

(a) x²+3x+2 = x²+x+2x+2 = x(x+1)+2(x+1) = (x+2) (x+1)

(b) x²-4 = x²-2² = (x+2) (x-2)

Now, a= (x+2) (x+1)
b= (x+2) (x-2)

LCM = (x+2) (x+1) (x-2)
Similarly, we need to find the second one
sorry but I am not able to find the correct answer yet but as soon as I get it I will send it to you ....
May be you got a clue how to do it

Sorry for that
If you get it from someone else then please do share the knowledge with me
