Question

The LCM of (a + b) and (a - b) is:
a) (a + b) (a + b)(a - b)
b) (a + b) (a? +b?) (a + b)
c) (a + b )(a + b + ab) (a + b)
d) (a + b°) (a - b) (a - b)​

Answer 1

The LCM of (a + b) and (a - b) is:

The LCM of (a + b) and (a - b) is:a) (a + b) (a + b)(a - b)

The LCM of (a + b) and (a - b) is:a) (a + b) (a + b)(a - b)b) (a + b) (a? +b?) (a + b)

The LCM of (a + b) and (a - b) is:a) (a + b) (a + b)(a - b)b) (a + b) (a? +b?) (a + b)c) (a + b )(a + b + ab) (a + b)

The LCM of (a + b) and (a - b) is:a) (a + b) (a + b)(a - b)b) (a + b) (a? +b?) (a + b)c) (a + b )(a + b + ab) (a + b)d) (a + b°) (a - b) (a - b)
