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:

0

Step-by-step explanation:

=(2-2)(2+2)+(2-2)(2+2)+(2-2)(2+2)=0

=(0×4)+(0×4)+(0×4)=0

=0+0+0=0

= 0=0

LHS=RHS

Answer 2

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
