Given:
The pair of expressions in the options.
To find:
The pair that shows equivalent expressions.
Solution:
We have,
By using distributive property, we get
So, option A is incorrect and option B is correct.
We have,
By using distributive property, we get
So, options C and D both are incorrect.
Therefore, the correct option is B.
The standard form is:
Degree = 5, leading coefficient=4
The 5th degree polynomial is:
Quintic function
it is a trinomial
<u>What is standard form of a polynomial?</u>
When expressing a polynomial in its standard form, the greatest degree of terms are written first, followed by the next degree, and so on.
So, standard form is:
To find the degree of the polynomial, add up the exponents of each term and select the highest sum ( if there are more than 1 variable in single term) or highest power of variable
Degree = 5
In a polynomial, the leading term is the term with the highest power of x.
So, leading coefficient=4
The 5th degree polynomial is:
Quintic function
It has 3 terms. so, it is a trinomial
