The long division below shows the first term of the quotient. which polynomial should be subtracted from the dividend first?
x^2

x + 2 ) x^3 + 3x^2 + x

a. x + 3
b. x^2 + x + 2
c. x^3 + 2x^2
d. x2 + 3x

Option C. x³ + 2x²

Step-by-step explanation:

In this long division x + 2 ) x³ + 3x² + x

when we divide the polynomial by (x + 2) then first quotient will be x². By the multiplication of (x + 2) and x² we get a polynomial which will be subtracted from the dividend.

(x + 2)×(x²) = x³ + 2x²

This is the polynomial to be subtracted.

Therefore option C is the correct answer.

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
