Question

16n^2-1=0

n=?
solve and check help please

Answer 1

Hint: Use the difference of squares factoring rule

a^2 - b^2 = (a-b)(a+b)

Answer 2

(4n+1)(4n-1)??

Answer 3

good, so

16n^2-1=0

turns into

(4n+1)(4n-1) = 0

Answer 4

Now use the zero product property to break up that last equation to get

4n+1 = 0 or 4n-1 = 0

Answer 5

So the answer would be -4/1,4/1

Answer 6

close, but no

Answer 7

4n+1 = 0

4n =-1

n = -1/4

---------------

4n -1 = 0

4n = 1

n = 1/4

So the solutions are n = -1/4, n = 1/4

Answer 8

cool thank you that makes sense thanks alot for breaking it down
