Answer: m = [tex]\frac{-1}{4}[/tex] or m = [tex]\frac{-7}{2}[/tex]

Step-by-step explanation:

Step 2: Subtract 8m^2+19m+13 from both sides.

−11m+6−(8m2+19m+13)=8m2+19m+13−(8m2+19m+13)

−8m2−30m−7=0

Step 3: Factor left side of equation.

(−4m−1)(2m+7)=0

Step 4: Set factors equal to 0.

−4m−1=0 or 2m+7=0
