Answer 2

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.
