(x+5)^2 - 64 = 0
(x+5)^2 - 8^2 = 0
(x+5-8) (x+5+8) = 0
(x-3) (x+13) = 0
=> x = 3 or x = -13
=> smaller x = - 13 & larger = 3
Remember
so
notice that 200=2*2*2*5*5, so x cannot be a whole number
take the log base 10 of both sides
divide both sides by
if we used
instead of
we would get
because

The inequality given is;
y < -6x +5
Use a graph tool to visualize this as attached
The equation is the following
This is a difference of two squares, the first one being the square of
, the second one being the square of
. The difference of two squares can be factorized as
If we apply this rule to our equation, we find
