Using proper identity, find the value of (1.2)2 – (0.8)2.

1.	Using proper identity, find the value of (1.2)2 – (0.8)2.
Answer» (1.2)² – (0.8)² = (1.2 + 0.8) (1.2 – 0.8) (Using identity III) = (2) (0.4) = 0.8

Answer»

(1.2)² – (0.8)²

= (1.2 + 0.8) (1.2 – 0.8) (Using identity III)

= (2) (0.4)

= 0.8
