Find the value of the expression a? – b2 for a = 2 and b=1
docker41 [41]

Answer:a^2-b^2=3

Step-by-step explanation:

We need to find the value of the below expression i.e.

a^2-b^2 when a = 2 and b = 1.

So,

Put a = 2 and b = 1 in the above expression. So,

a^2-b^2=(2)^2-1^2\\\\=4-1\\\\=3

Hence, the value of the expression is equal to 3.
