Explanation:

[tex]\frac{2x\text{ - 3}}{x^2+6x+8}\text{ + }\frac{10}{x^2+x\text{ - 12}}[/tex]

Finding the LCM:

[tex]\begin{gathered} =\frac{(2x-3)(x^2+x-12)+10(x^2+6x+8)}{(x^2+6x+8)(x^2+x-12)} \\ =\frac{(2x)(x^2+x-12)-3(x^2+x-12)+10(x^2+6x+8)}{(x^2+6x+8)(x^2+x-12)} \\ =\frac{(2x^3+2x^2-24x)-3x^2-3x+36+10x^2+60x+80}{(x^2+6x+8)(x^2+x-12)} \end{gathered}[/tex][tex]undefined[/tex]
