Question

Divide 3x + x2 + 2x + 5 by 1+2x+x.



plz answer this question correctly​

Answer 1

Answer:

(3×+2×+2×+5)/(1+2×+×)

(7×+5)/(1+3×)

3×+1| 7×+5| 2

6×+2

--------

×+3

---------

Answer 2

Answer:

P(X) = 3X³ + X² + 2X + 5

G(X) = 1 + 2X + X² = X² + 2X +1

On dividing P(X) by G(X) we get,

X² + 2X +1 ) 3X³ + X² + 2X + 5 ( 3X -5

3X³ + 6X² + 3

0 - 5X² - X +5

-5X² - 0 9X +10

Remainder = 9X +10

And,

Quotient = 3X -5
