The first step to solving this is to collect the like terms in this equation,, which are all the numbers with an x variable attached to them.
8.5x = -25.5
Now all you need to do to find x is divide both sides of the equation by 8.5
x = -3
This means that in order to make this equation true,, x must be -3.

This graph is that of a parabola, which in turn represents a quadratic (2nd order) equation, also a polynomial. The domain of any and all polynomial(s) is "the set of all real numbers," or (-infinity, infinity).
1 whole should be the answer
