Question

On simplifying (a + b – 3) – (b – a +3) + (a – b + 3) the result is____​

Answer 1

Answer:

3a–b–3

Step-by-step explanation:

First you have to multiply + and – signs into Brackets.

The law of multiplication:

+ × + = +

– × + = –

– × – = +

As you see, the sign "+" does nothing with the Brackets, but the sign "–" will make the Brackets negative:

and there's just one "–" in the expression:

–(b–a+3) that turns into –b+a–3, so we got:

a+b–3–b+a–3+a–b+3 = 3a–b–3

Hope you got it.
