Question

(a+√b)(a-√b) what is the formula

Answer 1

Answer:

a^2-b is the formula

a^2-b

Answer 2

Answer:

$a^{2}-b$

Step-by-step explanation:

$(a+\sqrt{b}) (a-\sqrt{b})\\since (x+y)(x-y) = x^{2} -y^{2}\\x=a \\y=\sqrt{b}\\hence,\\\\(a+\sqrt{b}) (a-\sqrt{b})\\=(a)^{2}-(\sqrt{b} )^{2}\\\\=a^{2} -b$

Here is the required answer
