1/3X-4=3/4X+1 | I do not get the steps it takes long.<br>​
RoseWind [281]

Answer:

x=-12

Step-by-step explanation:

Start by getting all of the x values on one side and other to the other.

1/3x-3/4x=1+4

Now simplify. Because 1/3 and 3/4 do not have the same denominator, find the least common factor between 3 and 4 (which is 12) and make the fractions have denominators of 12.

4/12x-9/12x=5

-5/12x=5

x=5*(12/-5)=60/-5=-12

x=-12

If the length of a rectangle is x-2 and its area is 2x3 – 8x2 + 2x+12, it’s width would be what?
hram777 [196]
Width would have to be a quadratic
Use long division to find the other factor of the cubic polynomial P (x).
P (x) factors in case it is reducible over R[x]
if it weren't then P (x) mod R [x] would be a field
otherwise you could use the Eisenstein Criterion.
