Question

What is the least common denominator of the rational expressions below?A.4x3(x + 3)B.x3(x + 3)C.x2(x + 3)D.4x2(x + 3)

Answer 1

- The expression given is:

`(2)/(x^2)-(7)/(4x^2+12x)`

- To find the Least common denominator, we need to multiply the terms of both denominators together.

- This is done below:

`\begin{gathered} x^2*(4x^2+12x) \\ 4x^4+12x^3 \end{gathered}`

-Factorizing the result, we have:
