Question

If x+2 is a factor of 3x³ - ² + 2ax + a, then find 'a'.​

Answer 1

Step-by-step explanation:

Wolf-dog hybrid (hybrid for short) is a term used to describe an animal that is part wolf and part domestic dog. Dogs (Canis lupus familiaris) and wolves (Canis lupus) share an evolutionary past and thus share many physical and behavioral traits.

Wolves are wild animals, and they are shaped by evolutionary pressures that allow them to find food, keep themselves safe, and produce offspring. The genetics that they express in the environments they live in allow them to survive, without the help of humans (Addams, and Miller 2012)

Dogs evolved from wolves through a centuries-long process of domestication. Domestication is the process by which a wild animal adapts to living with humans by being selectively bred by humans over thousands of years.

Answer 2

Hi ,there

________________________________

By using factor theorem

(3x-2)=0

=>3x=2

=>x=2/3

Now, let f (x) =3x²+x²-2ax+a

=>f(⅔)=3(⅔)²+(⅔)²-2a(⅔)+a

=>f(⅔) = 3(4/9)+(4/9)-2a(⅔)+a

=>f(⅔) = (12/9) + (4/9)-2a (⅔)+a

=>f(⅔) = (16/9) -2a (⅔)+a

=> f = (16/9) -2a+a

=> f = (16/9)-a

=>a= 16/9

I hope this will help u
