We have the following polynomial:
This is a polynomial of the form 
. Following this rule to expand it, we have:
Applying common factor 
:
Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to
. Hence, the final simplification is:
For the first equation, I put it in y=mx+b form, so y=-3x-9
the second one is x=4
hope i helped
Answer:
n<2
Step-by-step explanation:
6.2n<2n+8.4
Move variable to the left hand side and change its sign
6.2n - 2n < 8.4
Combine like terms
4.2n < 8.4
divide both side by 4.2
n < 2
