Answer:

n= ±(7/2)

Step-by-step explanation:

So this answer isn't going to be pretty,

Set the equation equal to zero:

4n²-49=0

Add 49 from both sides:

4n²=49

Divide 4 from both sides:

n²=(49/4)

Square root both sides:

n= ±(7/2)

Thats the answer, because to include the plus or minus symbol.
