Answer:
Step-by-step explanation:
[tex]a^{2} - a\sqrt{b} + a\sqrt{b} - b^{2} \\= a^{2} - b^{2} or (a+b) . (a-b)[/tex]
Value of given multiply a² - b
Given that;
(a+√b)(a-√b)
Find:
Value of given multiply
Computation:
(a+√b)(a-√b)
Formula used;
⇒ (a + b)(a - b) = a² - b²
So,
⇒ (a+√b)(a-√b)
⇒ (a)² - (√b)²
⇒ a² - b
