Answer 1

Answer:

The simplified answer is 3/(4-x)

Step-by-step explanation:

Given : 3x + 12 / 16 - x² = ?

Solution :  3x + 12 / 16 - x²

3x + 12 = 3(x+4) and 16-x² is in the form a²-b² = (a+b)(a-b)

             = 3 ( x+4)/(4 - x) (4 +x)

            Divide numerator and denominator by x+4, we get

           = 3/(4-x)
