Question

- a -b -c is same as - a -(_____)​

Answer 1

Answer:

= -a - (b + c)

Step-by-step explanation:

We know that,

x - y = x + (-y) --- 1

= x - y - z

-y and -z has a common factor of -1

= x + (-1 × y) + (-1 × z)

Now taking the common factor (-1),

= x + (-1)(y + z)

From eq.1,

= x - (y + z)

Thus, from the above result,

-a - b - c

= -a - (b + c)

Hope it helped and you understood it........All the best
