Answer:
{ -6, -4, -2}
Step-by-step explanation:
Since x > - 8, x can be any number greater than - 8.
x = -7, -6, -5, -4,...
BUT, it can't be equal because it's not using this sign
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
1. { -10, -8, -6} can't be an inequality of x because it has -10, -8.
2.{ -8, 0, 8} can't be an inequality of x because of -8.
3.{ -9, 1, 7} can't be an inequality of x because -9 isn't greater than x.
ANSWER
EXPLANATION
We want to factor
out of
The first term is already having a factor of
The constant term which is the second term is not having a factor of
so we need to use a trick of multiplying and dividing by the same factor to obtain,
We can now factor
out of the right hand side to obtain,
Let us rewrite the right most fraction using the normal division symbol.
We simplify to obtain,
This further gives us,
