Verify the following:

(–21) × [(– 4) + (– 6)] = [(–21) × (– 4)] + [(–21) × (– 6)]

Dear Student

From the given equation,
Let us consider the Left Hand Side (LHS) first = (–21) × [(–4) + (–6)]
= (-21) × [-4–6] = (-21) × [-10]
= 210
Now, consider the Right Hand Side (RHS) = [(–21) × (–4)] + [(–21) × (–6)]
= [84] + [126]
= 210
By comparing LHS and RHS, 210 = 210
LHS = RHS
Hence, the given equation is verified.
