Question

Which algebraic expression is a polynomial?

4x2 – 3x + StartFraction 2 Over x EndFraction
–6x3 + x2 – StartRoot 5 EndRoot
8x2 + StartRoot x EndRoot
–2x4 + StartRoot 3 Over 2 x EndRoot

Answer 1

answer:-2

base must must not negative

Answer 2

b)-6$x^{3}+\sqrt{5}$. So b) -6$x^{3}+\sqrt{5}$ is a polynomial.

Step-by-step explanation:

• In mathematics, an algebraic equation composed of c=variables/ indeterminates and coefficients is termed as a polynomial.

• Based on the number of terms they possess, they may be either classified as a monomial, binomial or trinomial.

• Its general formula is = a$x^{n} + bx^{n-1} +c x^{n-2} ----$

The options we have are:

a)$4x^{2} + 2/x$

b)-6$x^{3}+\sqrt{5}$

c)$8x^{2} +\sqrt{x}$

d)$-2x^{4} +\sqrt[3]{2x}$

The only option that follows the general formula of a polynomial is b)-6$x^{3}+\sqrt{5}$. So b) -6$x^{3}+\sqrt{5}$ is a polynomial.
