x squared +17x+72/x+9
first, we need to factor out the equation on the top!
(x+9)(x+8)/x+9, now cancel out the x+9/x+9=1 so it would be x+8/1 or x+8!
*To factor out use this chart
**Make one of numbers under the product column is a and the others is b!
sum of 17 product of 72
72 72,1
38 36,2
27 24,3
22 18,4
18 12,6
17 8,9 (this is the one!)
now put it in the equation (x+a)(b+x), or (x+8)(x+9)
