Question

Which factor do u cancel from the numerator and denominator to simplify, x^2 + 3x - 4 / x^2 - 16 @hartnn @ganeshie8 @amistre64

Answer 1

x^2 + 3x - 4 = (x+4)(x-1) and x^2 - 16 = (x+4)(x-4)

Thus, your fraction is equal to (x+4)(x-1)/(x+4)(x-4). Like terms cancel each other, right?

yes so u cancel x + 4
