Answer:

[tex]4x^4-9x^3+x^2[/tex]

Step-by-step explanation:

Dividing the polynomial by 7x means dividing each term by 7x, as shown below:

[tex]\frac{28x^5-63x^4+7x^3}{7x}\\=\frac{28x^5}{7x}-\frac{63x^4}{7x}+\frac{7x^3}{7x}\\=4x^4-9x^3+x^2[/tex]

In dividing, we also used the property of exponents, shown below:

[tex]\frac{a^x}{a^y}=a^{x-y}[/tex]

So the answer is:  [tex]4x^4-9x^3+x^2[/tex]

Answer:

4x⁴- 9x³+x²  is the answer.

Step-by-step explanation:

We have given the polynomial.

28x⁵ - 63 x⁴ +7x³

We have to divide this polynomial by 7x.

Hence,

(28x⁵-63x⁴+7x³)/7x

Dividing each term of givin polynomial by 7x, we have

(28x⁵/7x) - (63x⁴/7x)+(7x³/7x)

(28x⁵-63x⁴+7x³)/7x = 4x⁴-9x³+x²

4x⁴- 9x³+x² is the polynomial after simplification.
