Question

15. If a = 3,b = 5 and c = 10, verify:

(i) a x (b -c) = ab - ac​

Answer 1

Answer:

-15= -15

Step-by-step explanation:

a X (b-c) = ab-ac

3 X (5 - 10) = 3*5 - 3*10

3 X -5 = 15 - 30

-15 = -15

Answer 2

Step-by-step explanation:

a x (b -c) = ab - ac

LHS

= a x (b -c)

= 3× (5-10)

= 3 × (-5)

= -15

RHS

= ab - ac

= 3×5 - 5×10

= 15 - 50

= (-35)

LHS ≠ RHS

(-15) ≠ (-35)

Hence not verified
