Question

please answer this question ​

Answer 1

Polynomials in standard form are

$4x^{7}-3x^{5}+6x^{2}-9x+28$

$8x^{5}-7x^{3}+4x+1$

$x^{4}+62x^{2}-120x+9$

Solution:-

The standard form of a polynomial is in descending order. The descending order means exponents are decreasing, from the most left to the most right.

Answer 2

$\large\underline{\sf{Solution-}}$

Standard form of polynomial means to express in descending order of powers.

Thus,

Polynomials in standard form are as follow :

$\rm :\longmapsto\:4x^{7} + {0x}^{6} -3x^{5} + {0x}^{4} + {0x}^{3} +6x^{2}-9x+28$

${\rm :\longmapsto\:8x^{5} + {0x}^{4} -7x^{3} + {0x}^{2} +4x+1}$

$\rm :\longmapsto\:x^{4} + {0x}^{3} +62x^{2}-120x+9$

Additional Information : -

The polynomial of degree 1 is called linear polynomial.

The polynomial of degree 2 is called quadratic polynomial

The polynomial of degree 3 is called cubic polynomial.

The polynomial of degree 0 is called constant polynomial.

The degree of 0 is not defined.
