How do I simplify this expression

(-3)(4x - 12)​

-12(x-3)

Step-by-step explanation:

If you are only trying to simplify, you can factor out a 4 from (4x - 12).

4(x-3)

now multiply the 4 and -3

-12(x-3)

Step-by-step explanation:

Remark

This is an example of the distributive property. -3 multiplies both the 4x and the -12. The minus sign between them is NOT destroyed.

-3 * 4x = -12x

-3 * -12 = 36

- 12x + 36

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.
