Factor z2 + 17z + 72.
Nadya [2.5K]
Hello!

It looks like you meant,
z^2+17z+72
Break the expression into two groups, that would imply splitting the 17.
=\left(z^2+8z\right)+\left(9z+72\right)
Let's start factoring.
First, factor the z from z^2+8z
Then, factor the 9 from 9z+72
We would be left with,
=z\left(z+8\right)+9\left(z+8\right)
Factor out the common term, which is (z+8)
=\left(z+8\right)\left(z+9\right)

Our final answer would be,
=\left(z+8\right)\left(z+9\right)

You can feel free to let me know if you have any questions regarding this!
Thanks!

elena-s [515]

Given that Juan Solez, a prominent painter, takes out a simple discount note for one year from River National Bank for $5,000.

Annual rate of interest on that amount is 8%.

Now we have to find about what is the amount of the discount and the proceeds.


Amount of discount will be just 8% of 5000

0.08 ( 5000 )= $400


Proceeds will be difference of original amount and discount so that will be 5000-400= $4600
