9. Verify the following:
(ii) (-23) {(-5)+(+19)} = (-23)*(-5) + (-23) (+19)​

Answer 1

Answer:

Here!

Step-by-step explanation:

By Factor Theorem

⇒ k(1)2–3(1)+k = 0

⇒ k−3+k = 0

⇒ 2k−3 = 0

⇒ k= 3/2

Answer 2

Step-by-step explanation:

Solution:

(-23) {(-5)+(+19)} = (-23)*(-5) + (-23) (+19)

=> (-23) (19-5) = ( 23×5 ) - ( 23× 19)

=> (-23)×14 = 115 - 437

=> - 322 = - 322

so, LHS = RHS . VERIFIED.
