Answer 1

(1) Using the identity (a + b) (a − b) = a² − b²:

(2) Using the identity (a + b) (a − b) = a² − b²:

(3) Using the identity (a + b) (a − b) = a² − b²:

(4) Using the identity (a + b) (a − b) = a² − b²:

(5) Using the identity (a + b) (a − b) = a² − b²:

(6) Using the identity (a + b) (a − b) = a² − b²;

(7) Using the identity (a + b) (a − b) = a² − b²:

(8) Using the identity (a + b) (a − b) = a² − b²:

(9) Using the identity (a + b) (a − b) = a² − b²:

(10) Using the identity (a + b) (a − b) = a² − b²:
