Question

(𝑎 + 𝑏)² =

𝑎² + 𝑏²
𝑎² + 𝑎𝑏 + 𝑏²
𝑎² + 2𝑎𝑏 + 𝑏²
𝑎² − 𝑎𝑏 + 𝑏²

hint Hint:

The methods used to find the product of binomials are called special products.
Multiplying a number by itself is often called squaring.
For example (x + 3)(x + 3) = (x + 3)2

The correct answer is: 𝑎² + 2𝑎𝑏 + 𝑏²

(a+ b)² can be written as (a + b)(a + b)
(a + b)(a + b) = a(a + b) + b(a + b)
= a(a) + a(b) + b(a) + b(b)
= a² + ab + ab + b²
= a² + 2ab + b²
Final Answer:
The simplified value of (𝑎 + 𝑏)² is 2ab + b². Hence, option c is correct.
