What is the complete factorization of the polynomial below. x^3-3x^2+x-3

(x-3)(x+i)(x-i)

Step-by-step explanation:

We apply grouping method

We group first two terms and last two terms

Take out GCF x^2 from first group. Also take out 1 from second group

Now we factor x^2 + 1

We  use difference of square formula

a^2 - b^2 = (a+b)(a-b)

x^1 + 1 can be written as , the value of -1 is i^2

x^2 - i^2 = (x+i)(x-i)

Final answer is (x-3)(x+i)(x-i)

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
