I’m assuming you’re looking for a factored answer: 4(x+4)(x+1)
There are a total of 3 zeros in this measurement that are significant.

The answer=>
For this,we need to know what's Middle splitting method
- In order to factorize x² + bx + c we have to find numbers p and q such that p + q = b and pq = c. After finding p and q, we split the middle term in the quadratic as <em><u>px + qx and</u></em> get desired factors by grouping the terms.
Step-by-step explanation:

i.e
Alpha= Beta = 4
<u><em>Division and Multiplication.</em></u>
<u><em>Division is to check.SO multiplication is the correct answer.</em></u>
The length is gonna be 89 ft
72+72+89+89=322 ft
