Question 421433
"((4x^2 - 16)/(2-x)).  Again worked hard, I know the answer is  -4(x + 2) but I am not getting the steps to that answer."


4x^2 - 16
---------
2 - x


4(x^2 - 4)
---------- {factored 4 out of top, and flipped bottom around}
-x + 2


4(x + 2)(x - 2)
--------------- {factored top into two binomials, and factored -1 out of bottom}
-1(x - 2)


= -4(x + 2) {cancelled x - 2 on top and bottom}
