Simplify the following 2 {b}^(2) - 4b + 1 - {b }^(2) - b - 4 {b}^(2) - 2b + 6 ​

Question

Simplify the following


`2 {b}^(2) - 4b + 1 - {b }^(2) - b - 4 {b}^(2) - 2b + 6`
​

Answer 1

To simplify the given expression, let's combine like terms and simplify each term:

2b² - 4b + 1 - b² - b - 4b² - 2b + 6

Combine like terms:

(2b² - b² - 4b²) + (-4b - b - 2b) + (1 + 6)

Simplify each term:

(-3b²) + (-7b) + (7)

The simplified expression is:

-3b² - 7b + 7
