Use the Remainder Theorem to find the remainder for (2x^3-3x^2+6)/(x-1) and state whether or not the binomial is a factor of the

Bezzdna [24]

Answer:

Remainder= 5, and the binomial $(x-1)$ is not a factor of the given polynomial.

Step-by-step explanation:

Given polynomial is $(2x^3-3x^2+6)$ , we have to divide this with a binomial [tex}(x-1)[/tex] using remainder theorem.

Remainder theorem says if $(x-a)$ is a factor then remiander would be $f(a)$

Therefore for $(x-1), \ {we find}\ f(1)}$

$f(1)=(2\times 1^3-3\times1^2+6)\\1^3 =1\\1^2=1\\Substituting \ this \ above\\f(1)= (2-3+6)=5$

Thus the remainder is 5 and since it is not 0 , so the binomial $(x-1)$ is not a factor of the given polynomial.

What’s the element?

FromTheMoon [43]

Explanations and Steps:

How to find the elements:

*Take every element (either one capital letter OR two letters with the first capital and second lowercase)

*Reference the periodic table to find the element name

The number of reactants:

*Reactants are on the left side, what there is before the reaction

*Each reactant is separated by the + sign

*They may be more than one element

The number of products:

*Products are on the right side, what there is after the reaction

*Each product is separated with the + sign

*They may be more than one element

Is it balanced:

Count the number of each element on both sides. It is balanced if both sides have the same number of every element.

*Write out each of the element symbols for each side

*Remember the multiply subscripts (little numbers) by coefficients (big numbers)

Answers:

6.

The elements are:

H - hydrogen

Cl - chlorine

Ca - calcium

O - oxygen

# of reactants: 2

# of products: 2

Is it balanced?

Reactants:

H 4

Cl 2

Ca 1

O 2

Products:

H 2

Cl 2

Ca 1

O 1

It's not balanced because H and O have different numbers of atoms in the reactants and products.

7.

The elements are:

K - potassium

Cl - chlorine

O - oxygen

# of reactants: 1

# of products: 2

Is it balanced?

Reactants:

K 1

Cl 1

O 3

Products:

K 1

Cl 1

O 2

It's not balanced because there are three oxygen atoms for reactants but only two oxygen atoms in the product.

8.

The elements are:

K - potassium

P - phosphorus

O - oxygen

H - hydrogen

Cl - chlorine

# of reactants: 2

# of products: 2

Is it balanced?

Reactants:

K 3

P 1

O 4

H 1

Cl 1

Products:

K 3

P 1

O 4

H 3

Cl 3

It's not balanced because H and Cl have different numbers of atoms.

9.

The elements are:

S - sulphur

O - oxygen

# of reactants: 2

# of products: 1

Is it balanced?

Reactants:

S 2

O 6

Products:

S 2

O 6

It's balanced because both sides have 2 sulphur atoms and six oxygen atoms.

10.

The elements are:

K - potassium

I - iodine

Pb - lead

N - nitrogen

O - oxygen

# of reactants: 2

# of products: 2

Is it balanced?

Reactants:

K 2

I 2

Pb 1

N 2

O 6

Products:

K 1

I 2

Pb 1

N 1

O 3

It's not balanced because K, N and O have different numbers of atoms.
