Answer:


A. \;x^2 -7x + 1


B.\;5x^2 + 2x

Explanation:

Standard Form of Polynomial
Standard form of a polynomial is written in the descending order of the power of the variable.

The standard form of polynomial is given by


f(x) = a_nx^n + a_(n-1)x^(n-1)+....... + a_1x + a_0
where
x is the variable and
a_i,\; i = 0...n are coefficients.

The only two expressions in standard form are

A. \;x^2 -7x + 1

and

B.\;5x^2 + 2x (here the constant a₀ is 0)
