Question

Find all the zeroes of the polynomial 2x4+x3-14x2-19x-6

Answer 1

Putting x=(-1)

Gives answer 0

That means x+1is a factor.

Putting x=(-2)

Gives 0

That means x+2 is also a factor.

Multiple both binomials

----->x^2+3x+2

Divide given equation by this.....

After dividing factor the quotient

So the factors are....

1. x+1

2. x+2

3. 2x+1

4. x-3

HOPE THIS HELPS U......

Answer 2

Answer:

Step-by-step explanation:f(x)=2x^4+x^3-14x^2-19x-6

-2 and-1 are two zeroes of the polynomial.

(x-2)(x-1) =x^2-3x+2

Divide 2x^4+x^3-14x^2-19x-6 by x^2-3x+2.
