What is the answer to the equation 4n^2-49? w

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.

Step 1:
Find the difference between the two numbers.
$2.40-$1.44= $0.96

Step 2:
Divide by the original number.
$0.96/1.44= 0.667

Step 3:
Multiply by 100 to find percent increase.
0.667 * 100= 66.7% rounded to one decimal place or 67% rounded

Hope this helped! :)
