Best ResponseYou've already chosen the best response.0\[\frac{ (x^2 16) }{ (x+4) }\] you can factor the numerator in a way so as to get two expressions one of which will be (x+4) which will cancel out with the denominator

Best ResponseYou've already chosen the best response.0so in other words (x+4)(?) = (x^2  16)

Best ResponseYou've already chosen the best response.0x^2  16 is the difference of 2 squares x^2 is a perfect square and so is 4

Best ResponseYou've already chosen the best response.0are you familiar with the difference of squares method (its the way to factor expresions like these )

Best ResponseYou've already chosen the best response.0yeah but its a real number right

Best ResponseYou've already chosen the best response.0basically it means that if your constant (in this case the 16) is a perfect square you can factor the expression by multiplying two expressions which's constant is the perfect square of your original constant

Best ResponseYou've already chosen the best response.0umm no , what number squared equals 16

Best ResponseYou've already chosen the best response.0no what number when multiplied by itself equals 16 like 3 * 3 = 9 So 3 is the square root of 9.

Best ResponseYou've already chosen the best response.0correct which means that \[\sqrt{16} = 4\] and because 4 is a whole number we call 16 a perfect square
