Answer:
(x-1) × (32+2-3) = 31x - 31
Step-by-step explanation:
(x-1) × (32+2-3)
= (x-1) × 31
= (31 × x) - (31 × 1)
= 31x - 31
If x = -1
then,
(x-1) × (32+2-1) 31x - 31
= ((-1)-1) × 31 = ( 31 × (-1)) - 31
= (-2) × 31 = -31 -31
= (-62) = -62
-62 = -62
LHS = RHS
Therefore, (x-1) × (32+2-3) = 31x - 31 verified.
