Answer:
8x-40
Step-by-step explanation:
Multiplicity is how many times a root repeats
factor
x(x²-8x+16)
what times wat =16 and adds to -8
-4 and -4
x(x-4)(x-4)
x(x-4)²
set to zero
x=0
x-4=0
x=4
roots are 0 ad 4
4 repeats 2 times, so has a multiplicty of 2
so
roots are 0, and 4 multiplicity 2
18 is 60 percent of 30. 3 percent is 10 percent of 30 so 3 x 6 equals 18.
