This is the equation we were
given to solve.
We began by cleaning up the ex-
pression on the left side of the
equation. Using the commuta
tive and associative properties
of multiplication, we pulled the
negative sign to the front and
completed the multiplication of
the 5 and the 3r to get the
first factor of -152². We left
the other two factors alone since
there was not anything we could
do to simplify them. Now that
the left side of the equation is as
simplified as possible and is in
factored form, we are ready to
continue.
Using the zero product property,
we set each factor on the left side
of the equation equal to zero to
solve the equation.
We solved the first equation by
first dividing both sides by -15
and then taking the square root
of both sides of the equation,
paying attention to include both
the positive and negative root.
