  1. Polynomials are:
    A ) 7 x^7 - x - 5
    C ) 4 x + √ x - 1
    D ) x/5 + 2

    2. Polynomials are:
    A ) x² - x √2
    C ) 2 + s
    D ) 4 x³ + y

    3. The polynomial: - 5 x³ - 4 x + 1 is:
    C ) Cubic trinomial.

    4.  The degree of the polynomial: - 2 x² y^4 - 1/2 z is:
    C ) 4

Polynomials are:   (x² - x√2
), (2 + s  ), (4 x³ + y).

The given polynomial is \(-5x^{3} -4x+ 1\) is the cubic trinomial.

The highest power of polynomial is \(-2x^{2} -y^{4} -\frac{1}{2z}\) is 4.

  • A polynomial is a mathematical expression that contains two or more algebraic terms that are added, subtracted, or multiplied (no division allowed!).

Then, , \(4x + \sqrt{x} - 1\) a polynomial.

\(7x^{7} - x -5\) be a polynomial .


35x² is a monomial here (Polynomial with 1 degree).

\(\frac{x}{5} + 2\) is a polynomial.

  • Polynomials are:   x² - x√2
    , 2 + s  , 4 x³ + y.

  • A cubic equation is one of the form \(ax^{3} + bx^{2} + cx +d = 0\) where a, b, c and d are real numbers.

So, The given polynomial is \(-5x^{3} -4x+ 1\) is the cubic trinomial.

  • A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.

So, The highest power of polynomial is \(-2x^{2} -y^{4} -\frac{1}{2z}\) is 4.
