Question

Verify a (b – c) = a x b – a x c for a = - 3, b = 7, & c = -9​

Answer 1

Answer:

a (b – c) = a x b – a x c

-3 {7-(-9)} = -3 × 7 - (-3) × (-9)

-3 (7+9) = -21 - 27

-3 (16) = -48

-48 = -48

Hence proved.....

Answer 2

Answer:

$- 3(7 + 9) = - 3 \times 7 - ( - 3) \times( - 9) \\ - 3(16) = - 21 - 27 \\ - 48 = - 48$

LHS=RHS

Hence Verified
