-2b - 5a
Explanations:The given expression will be expressed mathematically as:
[tex]\frac{4ab+10a^2}{-2a}[/tex]Factor 2a out from the numerator
[tex]\frac{2a(2b\text{ + 5a)}}{-2a}[/tex]2a at the denominator cancels the 2a at the numerator.
The negative sign at the denominator also goes up to the numerator
The expression then becomes:
[tex]-(2b\text{ + 5a)}[/tex]Multiply both terms in the bracket by (-)
The expression then becomes -2b - 5a
