Question

Divide the following by -2a:4ab+10a²

Answer 1

Answer:

-2b - 5a

Explanations:

The given expression will be expressed mathematically as:

`(4ab+10a^2)/(-2a)`

Factor 2a out from the numerator

`\frac{2a(2b\text{ + 5a)}}{-2a}`

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:

`-(2b\text{ + 5a)}`

Multiply both terms in the bracket by (-)

The expression then becomes -2b - 5a
