When [tex]$36x^4 + 12x^8$[/tex] is divided by [tex]$12x^4$[/tex], the result is:

A. [tex]3 + 12x^8[/tex]

B. [tex]3 + x^4[/tex]

C. [tex]3x + x^2[/tex]

Answer :

To simplify the expression

[tex]$$\frac{36x^4 + 12x^8}{12x^4},$$[/tex]

we start by dividing each term in the numerator by the denominator:

1. For the first term:
[tex]$$\frac{36x^4}{12x^4} = \frac{36}{12}\cdot x^{4-4} = 3\cdot x^0 = 3.$$[/tex]
(Note that [tex]$x^0 = 1$[/tex].)

2. For the second term:
[tex]$$\frac{12x^8}{12x^4} = \frac{12}{12}\cdot x^{8-4} = 1\cdot x^4 = x^4.$$[/tex]

Now, adding the two results together gives:

[tex]$$3 + x^4.$$[/tex]

Thus, when [tex]$36x^4+12x^8$[/tex] is divided by [tex]$12x^4$[/tex], the simplified result is

[tex]$$3+x^4.$$[/tex]
