Explanation:

the standard form of a polynomial of degree 3 is

$y=a{x}^{3}+b{x}^{2}+cx+d;a\ne 0$

Expand the factors and collect like terms

$=(2x+4)(2{x}^{2}-7x-4)$

$=4{x}^{3}-14{x}^{2}-8x+8{x}^{2}-28x-16$

$=4{x}^{3}-6{x}^{2}-36x-16\leftarrow$ in standard form

Determine whether the following function is a polynomial function. If the function is a polynomial function, state its degree. If it is not, tell why not. Write the polynomial in standard form. Then identify the leading term and the constant term.

$g(x)=3-\frac{{x}^{2}}{4}$

Construct the augmented matrix that corresponds to the following system of equations.

$5+\frac{8x}{5}=y$

4z−3(x−4y)=0

5x−y=3(x−6z)

4z−3(x−4y)=0

5x−y=3(x−6z)
