• Expand (2a + b)²:
(2a + b)²
= (2a + b) · (2a + b)
Multiply out the brackets by applying the distributive property of multiplication:
= (2a + b) · 2a + (2a + b) · b
= 2a · 2a + b · 2a + 2a · b + b · b
= 2²a² + 2ab + 2ab + b²
Now, group like terms together, and you get
= 2²a² + 4ab + b²
= 4a² + 4ab + b² <——— expanded form (this is the answer).
I hope this helps. =)

Step-by-step explanation:
8 is a<u> Natural number, </u><u>Whole number, Integer and Real number</u>
<h3>What is an integer?</h3>
An integer is a number that cannot be expressed as fraction. They are known as whole numbers.
For natural numbers, they are value that starts from 1 and above. Since 8 is greater than 1, hence it is a natural number.
Real number includes both fractions and whole numbers, hence 8 is also a real number.
Based on the explanation, we can conclude that 8 is a<u> Natural number, </u><u>Whole number, Integer and Real number</u>
