Question

Answer the following questions: (4 marks) a) Verify the following: (2 – 2) (2 + 2) + (2 − 2) (2 + 2) + (2 − 2) (2 + 2) = 0​

Answer 1

Answer:

−21)×[(−4)+(−6)]=[(−21)×(−4)]+[(−21)×(−6)]

Taking   LHS   we   have  

(−21)×[(−4)+(−6)]

=(−21)×[−4−6]

=(−21)×(−10)

=210

Now ,  Taking   RHS   we   have  

[(−21)×(−4)]+[(−21)×(−6)]

=84+126

=210

Hence ,   LHS  =   RHS
