Question

Which shows the rational expression written using the least common denominator? x-2/x^3 + x + 1/2x^3

Answer 1

We have been given an expression:

(x - 2)/(x ^ 3) + (x + 1)/(2x ^ 3)

We will take the least common facto of the two expression which is 2x ^ 3

(2(x - 2) + (x + 1))/(2x ^ 3)

(2x - 4 + x + 1)/(2x ^ 3)

(3x - 3)/(2x ^ 3)

OR

3 2x^ 2 - backslash frca * 32x ^ 3 .
