Using synthetic division, find (x^4 − 2) ÷ (x + 1).

1 answer:

6 0

-1 | 1 ... 0 ... 0 ... 0 ... -2
... | ...... -1 .. 1 ... -1 ... 1
-------------------------------
... | 1 ... -1 .. 1 ... -1 | -1

In other words,

$\dfrac{x^4-2}{x+1}=x^3-x^2+x-1-\dfrac1{x+1}$

Using the 4 train car strategy for factoring polynomials, what is the green common factor for the 1st two train cars and the gre

koban [17]

The completely factored expression of 2x^2 + 4x + 3xy + 6y is (2x + 3y)(x + 2)

<h3>How to factor the polynomial?</h3>

The expression is given as:

2x^2 + 4x + 3xy + 6y

Group the expression into two

[2x^2 + 4x] + [3xy + 6y]

Factor out each group

2x(x + 2) + 3y(x + 2)

Factor out x + 2

(2x + 3y)(x + 2)

Hence, the completely factored expression of 2x^2 + 4x + 3xy + 6y is (2x + 3y)(x + 2)

Form a polynomial whose real zeros and degree are given.

Hitman42 [59]

Answer:

Step-by-step explanation:

Given that zeroes of a polynomial are

-3, -1, 1, 4

Degree of the polynomial is 4

Also leading coefficient is 1.

So we find easily the polynomial

Since polynomial is 0 at the given four points the polynomial is a product of

$(x+3)(x+1)(x-1)(x-4)\\=(x^2-1)(x^2-x-12)\\= (x^4-x^3-13x^2+x+12)$

Since leading coefficient is given to be 1 we need not multiply an arbitrary constant a

so the required polynomial is

$(x^4-x^3-13x^2+x+12)$
