Question

Please help:)
The H.C.F. of two expressions is x & their L.C.M is\[\large{x^3-9x}\]If one of the expressions is \[\large{x^2+3x}\], then the other expression is???
@jim_thompson5910 @experimentX :)

Answer 1

\[ x^3 - 9x = x(x^2 - 3^2) = x(x+3)(x - 3) \\
x^2 + 3x = x(x+3)\]

Answer 2

It's \[x^2-3x\]in my book:\

Answer 3

Answer 4

I don't want to disturb but @satellite73

Answer 5

Hint:

LCM = [ (Expression 1)*(Expression 2) ]/(HCF)

Answer 6

what is missing from \(x(x+3)\) to get \(x(x+3)(x-3)\)?

Answer 7

(x-3)

Answer 8

yup

Answer 9
