If negative sign precedes a bracket the sign of the terms inside the b...
Explanation:
When a negative sign precedes a bracket, it means that the negative sign is being multiplied by all the terms inside the bracket. This can be represented as follows:
-(a + b) = -1 × (a + b)
To simplify the expression, we can distribute the negative sign to each term inside the bracket:
= -1 × a - 1 × b
= -a - b
Therefore, when a negative sign precedes a bracket, the signs of all the terms inside it are changed.
