Question

Verify a x (b – c) = a x b – a x c by using examples of three integers as a, b and c.

Answer 1

Answer:

for example,

a,b and c are integer

a=2, b=4 , c= 6 and let x be variable

2x(4 - 6)

=8x - 12x

Answer 2

Step-by-step explanation:

verification :

Let a,b,&c be three integers (positive) 2 , 3 , 4 respectively.

Then ,

LHS :

a ×( b - c) = 2×(3-4)

=>2(-1)

=>-2

RHS :

a×b-a×c = 2×3-2×4

=>6-8

=>-2

.•. LHS = RHS

Again let a, b &c be three negative integers -2,-3,-4 respectively.

Then,

LHS :

a×(b-c) = -2 ×(-3+4)

=> -2×1

=> -2

RHS :

a×b-a×c = (-2×-3)-(-2×-4)

=>6-8

=> -2

.•. LHS = RHS
