Question

Using long division method, show that (3x + 2) is a factor of the polynomial
(11x + 20x^2 + 12x^3 + 2).​

Answer 1

Answer:

4x^2+4x+1 is the answer

Step-by-step explanation:

Answer 2

yes , (3x + 2) is a factor of the polynomial 12x³ +20x²+11x+2

Step-by-step explanation:

given polynomial is 11x + 20x²+12x³ +2

rearranging the polynomial we get

12x³ +20x²+11x+2

now on dividing the polynomial  12x³ +20x²+11x+2  by 3x+2  using long division method

we get the

quotient = 4x²+4x+1

remainder = 0

since , we get the remainder is 0 that means , 3x+2 is the factor of the polynomial l  12x³ +20x²+11x+2

hence proved
