What is the sum of the polynomials?(7x3 – 4x2) + (2x3 – 4x2)

a)5x3
b)9x3
c)5x3 – 8x2
d)9x3 – 8x2

Answers

Answer 1
Answer:

If you have to find the sum of the polynomials (7x^3 - 4x^2) + (2x^3 - 4x^2)=7x^3-4x^2+2x^3-4x^2, then you have:

1. group all terms that have equal degrees

7x^3+2x^3 \text{ and } -4x^2-4x^2.

2. Add the coefficients near terms of equal degree

7+2=9,

-4-4=-8.

3. Write the sum as 9x^3-8x^2.

Answer: correct choice is D.
Answer 2
Answer: (7x3 – 4x2) + (2x3 – 4x2) = 9x3 – 8x2

Which statement is true? All constants are of degree 0. All monomials are of degree 1. All binomials are of degree 1. All trinomials are of degree 3.

Answers

Among the statements only the First statement is true, All constants are of degree 0. Because monomials can have any degrees while binomials will always be in the 1 degree. Also, trinomials will always have a degree of 2.

Answer:

Option 1 is correct.

Step-by-step explanation:

Given the following statements we have to choose the true statement.

First option: All constants are of degree 0

The constant term of a polynomial is the term in which the variable does not appear i.e no variable include in that term i.e of degree 0.

Second option: All monomials are of degree 1

Monomials are the polynomials containing 1 term not necessarily of degree 1. Hence, the above statement not true.

Third option: All binomials are of degree 1

Binomials are the polynomials containing 2 term not necessarily of degree 1. Hence, the above statement not true.

Fourth option: All trinomials are of degree 3

Trinomials are the polynomials containing 3 terms not necessarily of degree 3. Hence, the above statement not true.

Hence, option 1 is correct.
