Question

prove that
a cude+ b cude = (a+b) (a²+b²- ab)​

Answer 1

Answer:

Finally, Last means we multiply the last terms of each expression, which are b and −b , so their product is −b2 .

Now, we can finally put everything together;

(a+b)(a−b)

=a2−ab+ba+(−b2)

=a2−ab+ab−b2

=a2−b2

Therefore, by expanding and simplifying, we have shown that

a2−b2=(a+b)(a−b) .

Answer 2

Answer:

Hope you get the correct answer.
