Answer 1

10m^2-1 solved on calculater

Answer 2

The answer is 10m² - 1

Explanation:

1) Remove parentheses.

`{4m}^(2) - {5m}^(4) - 5 + {5m}^(4) + {6m}^(2) + 4`

2) Collect like terms.

`( {4m}^(2) + {6m}^(2) ) + ( - {5m}^(4) + {5m}^(4) ) + ( - 5 + 4)`

3) Simplify.

`{10m}^(2) - 1`

Therefor, the answer is 10m² - 1.
