Question

Which polynomial is in standard form? a)2xy^3 +3x^3 y^4 -4x^4 y^5 +9x^5 y^6 b)8x^5 -5y^4 -2xy^5 + x^2 y c)x^3 y^2 -3x^2 y-9x^4 y^3 +11x d)5x^7 y^2 + 7x^6 y^5 -14x^3 y^7 +51x^2 y^9

Answer 1

Answer:

d) $5x^7 y^2 + 7x^6 y^5 -14x^3 y^7 +51x^2 y^9$

Step-by-step explanation:

A polynomial is said to be in standard form if its terms are arranged in order of decreasing degree. That is the first term is of highest degree followed by the second term then the third term and so on. The terms of a standard polynomial are ordered from highest degree to lowest degree.

The polynomial $5x^7 y^2 + 7x^6 y^5 -14x^3 y^7 +51x^2 y^9$ is in standard form because the degree of x are arranged from highest degree to lowest degree.
