(–15) × [(–7) – (–1)]

= (-15) 
× [-7+1]
= (-15) × (-6)
= 90

(–15) × (–7) – (–15) × (–1)

= 105 - 15
=90

Yes (–15) × [(–7) – (–1)]  =  (–15) × (–7) – (–15) × (–1)

Yes, (–15) × [(–7) – (–1)] = (–15) × (–7) – (–15) × (–1) , the given equation is true.

Given :

The equation (–15) × [(–7) – (–1)] = (–15) × (–7) – (–15) × (–1)

To find :

To prove the equation

Solution :

L.H.S

(–15) × [(–7) – (–1)]

R.H.S

(–15) × (–7) – (–15) × (–1)

Solving L.H.S ,

(–15) × [(–7) – (–1)]

= (-15) × [(-7)+1]

= (-15) × (-6)

= 90

Solving R.H.S ,

(–15) × (–7) – (–15) × (–1)

= 105 - 15

= 90

Hence, L.H.S = R.H.S (proved)

Yes, (–15) × [(–7) – (–1)] = (–15) × (–7) – (–15) × (–1) , the given equation is true.
