Question

what is the simplified form of x^2-16/x+4 ?

Answer 1

Zero denominator expression makes the expression undefined [even though it's reducible]..

x + 4 = 0
x = -4

If we factor x² - 16, then we obtain:

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

Hence, the answer is x – 4,

Answer 2

whats the restriction of this problem?

Answer 3

i dont know :l

Answer 4

The restriction is that x can't equal -4

Answer 5

This is so the original expression and the result are equivalent
