What is the root of a problem?

If you mean a math problem, "root" is another word for "solution".The "root" of a polynomial in "x" is any value for "x" which will set the polynomial equal to zero, when evaluated.If you mean a math problem, "root" is another word for "solution".The "root" of a polynomial in "x" is any value for "x" which will set the polynomial equal to zero, when evaluated.If you mean a math problem, "root" is another word for "solution".The "root" of a polynomial in "x" is any value for "x" which will set the polynomial equal to zero, when evaluated.If you mean a math problem, "root" is another word for "solution".The "root" of a polynomial in "x" is any value for "x" which will set the polynomial equal to zero, when evaluated.


Which best describes a root of a polynomial?

A "root" of a polynomial is any value which, when replaced for the variable, results in the polynomial evaluating to zero. For example, in the polynomial x2 - 9, if you replace "x" by 3, or by -3, the resulting expression is equal to zero.


What is the least degree a polynomial could have with an imaginary root with a multiplicity of three?

Since the question did not specify a rational polynomial, the answer is a polynomial of degree 3.


Which mathematical term describes the x-value of a point where the graph of a polynomial crosses the x-axis?

A root or a zero of the polynomial.


How to tell if there are no real roots?

The real roots of what, exactly? If you mean a square trinomial, then: If the discriminant is positive, the polynomial has two real roots. If the discriminant is zero, the polynomial has one (double) real root. If the discriminant is negative, the polynomial has two complex roots (and of course no real roots). The discriminant is the term under the square root in the quadratic equation, in other words, b2 - 4ac.

A root.


Why does every polynomial have a real root?

1+x2 is a polynomial and doesn't have a real root.


Is x minus the square root of 11 a polynomial?

Yes, it is a linear polynomial.


Is the square root of x a polynomial?

No,


Is a polynomial with square root a polynomial?

It is a polynomial if the square root is in a coefficient but not if it is applied to the variable. A polynomial can have only integer powers of the variable. Thus: sqrt(2)*x3 + 4*x + 3 is a polynomial expression but 2*x3 + 4*sqrt(x) + 3 is not.

What is a root of a polynomial function?

A value of the variable that makes the polynomial equal to zero (apex)


Is the square root of x plus 2 a polynomial?

No. by definition, the polynomial should contain an integer as exponent and square root 1/2 is not an integer.
