Answer 1

`\text{ Option }\rightarrow\text{ C}`

Step-by-step explanation: We have to pick a polynomial that is in the standard form, the standard form can be written as follows:

`P(x)=ax^n+bx^(n-1)+cx^(n-3)+..+zx^(n-n)\rightarrow(1)`

Simplifying (1) to third-degree polynomial gives the following:

`P(x)=ax^3+bx^2+cx+d\rightarrow(2)`

By comparing all the options with the equation (2) we see that the following option is closest to the standard form:

`7x^2-6x^2-5x+3x\rightarrow\text{ Option \lparen C\rparen}`

Therefore the answer is Option(C).
