What is x^4-4x^3-32 in factored form

1 answer:

3 0

Factoring: x4-4x3+8x-32

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 8x-32
Group 2: -4x3+x4

Pull out from each group separately :

Group 1: (x-4) • (8)
Group 2: (x-4) • (x3)
-------------------
Add up the two groups :
(x-4) • (x3+8)

harina [27]

Answer: 1,817 minor earthquakes

Step-by-step explanation: First you make 89.1% and change it to a decimal. You do that by moving the decimal point over 2 spaces to the left. Next you take 16,674 and divide it by 0.891. Once you get that number you subtract 16,674 by your new number from when you divided to get your answer.
