Question

How do we Simplify each sum

Answer 1

Answer:

The answer is 10m² - 1

Step-by-step 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.
