The (a + b)² formula is used to find the square of a binomial. This formula is also used to factorize some special types of trinomials and is one of the algebraic identities. The (a + b) whole square formula is the result of the square of the sum of two terms a and b.

The (a + b)² formula is widely used to factorize the trinomials of the form a² + 2ab + b². This formula is explained below along with solved examples in the following section.

1. A ____________ is a circuit with only one output but can have multiple inputs.

2. There are 5 universal gates.

3. The Output is LOW if any one of the inputs is HIGH in case of a _________ gate.

4. The following figure shows a ___________ gate.

5. The complement of the input given is obtained in case of:

6. How many AND gates are required to realize the following expression Y=AB+BC?

7. Number of outputs in a half adder ?

8. The ________ gate is an OR gate followed by a NOT gate.

9. The expression of a NAND gate is?

10. Which of the following correctly describes the distributive law.
