2- 11x2 - 8x + 6x2
= 6x2-11x2 -8x +2
= -5x2 - 8x + 2 A

Answer:  

Option A that is [tex]-5x^2-8x+2[/tex]

Explanation:

Standard form of polynomial means the exponents should be in decreasing order

Degree is the highest power or exponent of the variable in the polynomial

Here, highest power is 2 after that 1 and then 0

so, we will write term of exponent 2 first, then of exponent 1  and then zero

Hence, [tex]-11x^2+6x^2-8x+2\\\\= -5x^2-8x+2[/tex]

Being highest degree 2 this is the quadratic and total number of terms are three in the expression hence, quadratic trinomial

Therefore, [tex]-5x^2-8x+2[/tex]; quadratic trinomial is the correct option.
