(3x^2 + 9x) / ( x^2 -2x -15)
Factor both polynomials
(3x)(x+3) / (x-5)(x+3) = 3x/(x+5)
The simplified form is 3x/(x+5)
The restriction for the variable is x ≠ -3 (this is because you can only simplify the factor x-3 if its value is not zero).

Answer:
Step-by-step explanation:
-(m - 6) = 3m + 14
-m + 6 = 3m +14
Subtract 6 from both the sides
-m + 6 - 6 = 3m + 14 - 6
-m = 3m + 8
Subtract 3m from both the sides.
-m - 3m = 3m + 8 - 3m
-4m = 8
Divide by (-4)
-4m/-4 = 8/-4
m = -2
