Is 1 x 2 2x 5 a polynomial or not?

yes, x2 + 2x -5 is polynomial in one variable because it contains only one variable which is x.

Is 1 X² 5x 6 a quadratic polynomial?

Answer Expert Verified polynomial . -1/( x²-5x+6 ) is not a polynomial.

Which is not a polynomial?

Polynomials cannot contain fractional exponents. Terms containing fractional exponents (such as 3x+2y1/2-1) are not considered polynomials. Polynomials cannot contain radicals. For example, 2y2 +√3x + 4 is not a polynomial.

Why 1 x 2 is not a polynomial give reason?

1/(x-2) is not a polynomial as this equals to (x-2)^-1, and negative powers are not allowed for a given equation to be a polynomial.

Is 6×2 a polynomial?

The three terms are not written in descending order, I notice. The 6×2, while written first, is not the “leading” term, because it does not have the highest degree. The highest-degree term is the 7×4, so this is a degree-four polynomial.

Is x² a polynomial?

They are zero polynomial, linear polynomial, quadratic polynomial, cubic polynomial. Polynomials should have a whole number as the degree. Expressions with negative exponents are not polynomials. For example, x-2 is not a polynomial.

What is a factor of x² 5x 6?

Answer: The Factors of x² – 5x + 6 are (x-3) (x-2)

Why 5 is a polynomial?

(Yes, “5” is a polynomial, one term is allowed, and it can be just a constant!) 3xy-2 is not, because the exponent is “-2” (exponents can only be 0,1,2,…)

What are the 3 polynomial?

Based on the number of terms in a polynomial, there are 3 types of polynomials. They are monomial, binomial and trinomial. Based on the degree of a polynomial, they can be categorized as zero or constant polynomials, linear polynomials, quadratic polynomials, and cubic polynomials.

Why X 1 X is not a polynomial?

It is not a polynomial because x-1/x can be written as x – x⁻¹ and polynomials cannot have negative powers on the variables.

Why is 1 x not a polynomial justify answer?

If you question is about x – (1/x) + 1 it still is not a polynomial because 1/x is equivalent to x^-1, which is a negative integer exponent in your expression.

Is -5x a polynomial?

(c) x 3−3x+1 is a polynomial. −5x is also not a polynomial, since the exponents of variable in 1st term is a rational number. Was this answer helpful?

Is 1/2x a polynomial?

1/2x is not a polynomial. It has 1 unique and important violation when considering the rules of polynomials. One key thing to remember is that the terms of a polynomial cannot be divided by a variable. In this case, the term is divided by the variable x.

Which equation is not a polynomial?

= x2 +x−1 is not a polynomial since the exponent of variable in 2nd term is negative. (b) 2×2 −3 x +1 = 2×2 −3×21 +1 is not a polynomial, since the exponent of variable in 2nd terms is a rational number.

What are the characteristics of a polynomial?

A polynomial can have constants, variables and exponents, but never division by a variable. Also they can have one or more terms, but not an infinitenumber of terms.
