zeros
values at which an equation equals zero are called roots,solutions, or simply zeros.
an x-intercept occurs when y=o
ex.) y=x squared - 4
0=(x-2)(x+2)
(-infinity,-2)(-2,2) (2,infinity)
That is an impossible equation, because it is stating that m has two values.
Find an equation of variation where y varies directly as x. One pair of values is y = 80 when x = 40
that would be limited to 3 and -3 for values of x
There is no property that justifies it. The equation is true for some values of x, not for others.
Generally, when we say a quadratic equation has no solutions, it means that the graph does not cross the x-axis at all.In other words, it means that there are no values for x when y equals 0 (because the line y=0 IS the x-axis.)Hope that helps.Jamz159
They are called the solutions or roots of the equations.
That is an impossible equation, because it is stating that m has two values.
They are called the "solutions" of the equation.
It is, in fact, an identity - which is an equation which is true for all values of the variable.
In math speak: Solving the equation means finding 'x' values that make the equation true. These 'x' values are called the roots of the quadratic.

An equation that is always true is an identity.
It is called the DOMAIN!
The answer in an equation is called the "solution." It is the value or values that satisfy the equation, making both sides equal when substituted into the expression. In the case of equations with multiple variables, the solution may represent a set of values.
There are no exclude values of the equation, as given.
