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

The complete factorization is (x^2 + 1)(x + 2)

Step-by-step explanation:

In order to find this, we start by splitting the 4 term polynomial into two, two-term polynomials. Then we pull out the greatest common factor of each.

x^3 + 2x^2 = x^2(x + 2)

x + 2 = 1(x + 2)

Since the remaining parentheses are identical, we use that and the two outside to factor.

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
