I can help you understand this, however there is nothing but 'M'
Answer:
y (x² + 1) (x² - 5)
Step-by-step explanation:
<h3>Factorization:</h3>
Take 'y' from each term.
x⁴y - 4x²y - 5y = y[x⁴ - 4x² - 5]
Now factorize x⁴ - 4x² - 5.
Sum = -4
Product = -5
Factors = -5 , 1
When we add (-5) + 1, it gives (-4) and when we multiply (-5)*1, gives (-5).
x⁴ - 4x² - 5 = x⁴ + x² - 5x² - 5
= x²(x² + 1) -5(x² + 1)
= (x²+ 1) (x² - 5)
x⁴y - 4x²y - 5y = y (x² + 1) (x² - 5)

Determine the values of x

Take square root of both sides


Expand 45 as 9 * 5

Split the square root



This can be further split to:
or 
Hence, the possible values of x are

Hey there! I'm happy to help!
We want to find to find the length of the wire that will go around the friends field. The distance around something is called the perimeter. To find this, we will take our two sides with the length of 219 and two sides with the width of 7525 and then add them.
2(219)+2(7525)=15488
Therefore, we will need a wire with a length of 15488.
I hope that this helps! Have a wonderful day!
