A:

Answer:[tex]m = -6 \ or \ m = -\frac{1}{4}[/tex]Step-by-step explanation:Given[tex]\frac{1}{m^2+7m+6}+\frac{m+3}{m^2+7m+6}= \frac{5}{m+6}\\[/tex]Simplifying the above equation we get:Step 1: Solving for common denominator term we get;[tex]\frac{1+m+3}{m^2+7m+6}= \frac{5}{m+6}\\\\\frac{m+4}{m^2+7m+6}= \frac{5}{m+6}[/tex]Step 2: Multiplying denominators on both side we get;[tex](m+4)(m+6)=5(m^2+7m+6)\\m^2+6m+4m+24 = 5m^2+35m+30\\m^2+10m+24 = 5m^2+35m+30\\5m^2+35m+30-m^2-10m-24=0\\4m^2+25m+6=0[/tex]Step 3: Now we need to find the factors of m.[tex]4m^2+25m+6=0\\4m^2+m +24m+6=0\\m(4m+1)+6(4m+1)=0\\(4m+1)(m+6)=0[/tex]Step 4: Solving for both terms we get;[tex]4m+1=0\\4m =-1\\m= - \frac{1}{4}[/tex]Also,[tex]m+6=0\\m=-6[/tex]Hence [tex]m = -6 \ or \ m = -\frac{1}{4}[/tex]
