Question

x^2-9x, x^2+9x

find LCM

Answer 1

@satellite73

Answer 2

LCM : x(x-9)(x+9)

Answer 3

thats the final answer?

Answer 4

taking commons out,
\[x^{2}-9x=x(x-9)\]
and \[x^{2}+9x=x(x+9)\]

now LCM=(common terms in both)*(remaining terms)

Answer 5

i dont get it

Answer 6

??

Answer 7

LCM=(common terms in both)*(remaining terms)
Both have x. and the remaining is (x-9) and (x+9)

So \(\text{LCM} = \boxed{x(x-9)(x+9)}\)
