In maths, something that is quadratic is squared. So a quadratic equation will have X squared in it.
Quadratic, simultaneous and straight line equations
Look in an advanced maths book.Improved answer:-If the discriminant of the quadratic expression is less than zero then it's not possible to factor it.
Piecewise, linear, exponential, quadratic, Onto, cubic, polynomial and absolute value.
The quadratic mean is a measure of the spread of values about their arithmetic mean. By definition, the arithmetic mean of the differences will be zero and so adds no information. Another measure is required and that is the quadratic mean.
Yes depending on the question for instance if the discriminant of a quadratic equation is less than zero then it will have no solutions.
Quadratic is an adjective that is used to describe something that is related to squares. For example, the quadratic equation uses squares, or the second power, and is thus quadratic.
A expression in maths is a collection of terms without an equality sign.
