Question

Simplify completely

Answer 1

\[\frac{ x ^{2} - 100 }{ x ^{2}-2x-120 } \div \frac{ 6x+60 }{ x-2 }\]

Answer 2

factorize x^2-2x-120

it can be written as (x-12)(x+10)
and X^2 - 100 = x^2 - (10)^2= (x+10) (x-10)

now try to solve it

Answer 3

what about the second part the 6x+60/x-2?

Answer 4

after you flip to x-2/6x+60 that would factorize into what?

Answer 5

you can write it as x-2/6(x+10)

Answer 6

after flipping you can cancel some terms.

Answer 7

would it be \[\frac{ x-2 }{ 6(x+12) }\]

Answer 8

it will be x-2/6(x-12)

Answer 9

ohh okay .. thank you!
