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

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.
