Answer:
A
Step-by-step explanation:
A polynomial is in standard form when its term of highest degree is first, its term of 2nd of next highest degree is 2nd etc..
Check all options:
A. Polynomial [tex]2x^5-3x^3-6x^2 + 7x + 9[/tex] is in standard form, because degrees are in descending order.
B. Polynomial [tex]2x^2-3x^3-6x^4 + 9x + 11[/tex] is not in standard form, because degrees are not in descending order. The standard form of this polynomial is [tex]-6x^4-3x^3+ 2x^2+ 9x + 11[/tex]
C. Polynomial [tex]8x-3x^3 + 6x^2 + 9x^5 + 10[/tex] is not in standard form, because degrees are not in descending order. The standard form of this polynomial is [tex]9x^5-3x^3 + 6x^2 +8x + 10[/tex]
D. Polynomial [tex]8-3x + 6x^2 + 9x^3 + 11x^4[/tex] is not in standard form, because degrees are in ascending order. The standard form of this polynomial is [tex]11x^4+9x^3+6x^2-3x+8[/tex]
