Question

3. Verify a x (b + c) = a x b + a x c,
(a) a=-1, b = -4, c = -2​

Answer 1

Answer:

-1( -4-2)= -1*-4 + (-1)(-2)

4+2=4+(1)(2)

6=4+2

6=6

hence, verified

Answer 2

Step-by-step explanation:

$verify \: \: \: a \times (b + c) = a \times b +a \times c$

$= lhs$

$= - 1( - 4 + ( - 2)) = - 1( - 6) = 6$

$= rhs$

$= - 1 \times - 4 + - 1 \times - 2 = 4 + 2 = 6$

$lhs = rhs \: \: hence \: proved$
