When is an equation quadratic?
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.
How are functions like linear equations?
Most functions are not like linear equations.

The quadric formula can be used to solve an equation only if the highest degree in the equation is?
2.
Most quadratic equations have?
two solutions
Most quadratic equations have what?
Two solutions
What are ways to represent linear equations?
One of the most common ways to represent linear equations is to use constants. You can also represent linear equations by drawing a graph.
Most quadratic equations have how many solutions?
2
Which is most likely the first step in solving a system of nonlinear equations by substitution APEX?

What has the author Anthony J Eiardi written?
Anthony J. Eiardi has written: 'An analytical classification of quadric surfaces'
What do the letters mean in algebraic equations?
The letters in most algebraic equations mostly represent the value of the number or often at times the gradient.
What are the different Types of mathematical equations?
Algebraic equations, trigenometric equations, linear equations, geometric equations, partial differential equations, differential equations, integrals to name a few.
What is a really cool app for naturally writing equations?
MIT has created this application that recognizes most written equations! Check out the link below and play around with it.
What is the classification of a system of equations?
The answer will depend on what kinds of equations: there are linear equations, polynomials of various orders, algebraic equations, trigonometric equations, exponential ones and logarithmic ones. There are single equations, systems of linear equations, systems of linear and non-linear equations. There are also differential equations which are classified by order and by degree. There are also partial differential equations.
