# Which expression can be used to find the difference between the polynomials? (4m – 5) – (6m – 7 + 2n)

# A. (4m – 5) + (6m – 7 + 2n) B. (4m – 5) + (6m + 7 + 2n) C. (4m – 5) - (6m - 7 + 2n) D. (4m + 5) + (6m + 7 + 2n)

Polynomials are algebraic expressions that have variables and coefficients with variables having positive integral powers.

## Answer: Option(c) can be used to find the difference between the polynomials. The difference between the polynomials (4m – 5) – (6m – 7 + 2n) is (-2m + 2 -2n)

Let's add the polynomials.

**Explanation:**

Given: difference of two polynomial,

(4m- 5) - (6m - 7 + 2n)

⇒ (4m - 5 - 6m - ( -7 ) - 2n)

⇒ ( 4m - 6m - 5 + 7 - 2n)

⇒ (-2m + 2 -2n)
