Question

can you solve the problem ​

Answer 1

Step-by-step explanation:

Let us see the proof of a square minus b square formula. To verify that a2 - b2 = (a - b) (a + b) we need to prove LHS = RHS. Let us try to solve the equation:

a2 - b2 = (a - b) (a + b)

Multiply (a - b) and (a + b) we get

=a(a+b) -b(a + b)

=a2 + ab - ba - b2

=a2 + 0 + b2

=a2 - b2

Hence Verified

a2 - b2 = (a - b) (a + b)
