A, b, and c are polynomials, where a = n, b = 2n 6, and c = n2 – 1. what is ab – c in simplest form? –n2 3n 5 n2 6n 1 2n2 6n – 1 3n2 5

Sagot :

The equations a = n, b = 2n + 6 and c = n² - 1 are polynomials, and the expression for ab - c is n² + 6n + 1

How to determine the expression for ab - c?

The polynomials are given as:

a = n

b = 2n + 6

c = n² - 1

The expression ab - c is calculated using:

ab - c = n * (2n + 6) - (n² - 1)

Expand

ab - c = 2n² + 6n - n² + 1

Collect like terms

ab - c = 2n² - n² + 6n  + 1

Evaluate

ab - c = n² + 6n + 1

Hence, the expression for ab - c is n² + 6n + 1
