Answer:
(m-5) (n-4)
Step-by-step explanation:
mn - 4m - 5n + 20
We will factor by grouping
mn -5n -4m +20
Factor an n out of the first 2 terms and a -4 out of the last 2 terms
n (m-5) -4(m-5)
Now factor out a m-5
(m-5) (n-4)

x³ + y³ + z³ - 3xyz is a multiple of x+y+z.
<h3>What is a multiple?</h3>
It should be noted that a multiple simply means a number that van be divided by another a certain number if times without a remainder.
Put x + y + z = 0
= x³ + y³ + z³ - 3xyx
= 0(x² + y² + z² - xt - yz - zx)
= x³ + y³ + z³ - 3xyz = 0.
x³ + y³ + z³ = 3xyz
