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.
