Solution

- The expression given is:

[tex]\frac{2}{x^2}-\frac{7}{4x^2+12x}[/tex]

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

- This is done below:

[tex]\begin{gathered} x^2\times(4x^2+12x) \\ 4x^4+12x^3 \end{gathered}[/tex]

-Factorizing the result, we have:
