Question 8442
There are several ways to solve this. If you use the quadratic equation  the use a = 1, b = 8 and c = 0. You can also factor this. Notice that {{{y^2 =y*y}}}. Let's rewrite the equation as follows:
{{{y^2 + 8y = y*y + 8y = 0}}}.
We can factor one y from the expression:
{{{y(y + 8) = 0}}}
This equation is true under two conditions. First, y = 0 and second, y = -8.
