When the equation is in one the following formats: ax2+ bx+c = 0 a(x+b)2+c = 0 (x+a)(x+b) = 0 than it is a quadric. It is also quadratic when x2 and only x2 is in it. example: x2 + 1= 0 and x2=0 are quadratic equations. However ax3+bx2+ cx+d =0 is not a quadratic, this is a cubic because of the x3 term, However you can use the quadric equation to find one of the two answers for it.
Because when your solving a quadratic equation your looking for x-intercepts which is where why equals 0 and x equals what ever the answer is.
r=0 is the solution...
y = 0" the answer is YES.

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2). In any case, the quadratic equation IS x2 ± 2x ± 13 = 0 (depending on what the signs in the question are).
y = 0" the answer is YES.
r=0 is the solution...
The equation 0 equals 0 is an identity and contributes absolutely nothing to the part of the graph that you should shade or not. The tautological statement can be ignored.
A linear equation.
Yes, the equation has a slope of 0.
No
root
It's an equation in 'N' ... about the simplest one you could write.The solution of that equation is: N=0 .
