Subtract – 3ab – 8 from 3ab + 8. Also, subtract 3ab + 8 from – 3ab – 8
उत्तर
Subtracting – 3ab – 8 from 3ab + 8
= 3ab + 8 – (– 3ab – 8)
= 3ab + 8 + (3ab + 8)
= 3ab + 8 + 3ab + 8
= (3 + 3)ab + (8 + 8)
= 6ab + 16
Also subtracting 3ab + 8 from – 3ab – 8
= – 3ab – 8 – (3ab + 8)
= – 3ab – 8 + (– 3ab – 8)
= – 3ab – 8 – 3ab – 8
= [(– 3) + (– 3)]ab + [(– 8) + (– 8)]
= – 6ab + (–16)
= – 6ab – 16
