Question

simplify (6-√2)(2+√5)​

Answer 1

6²-√2² {(a+b)(a-b)}= a²-b²

hence

36-2 (√ is considered as 2 so The 2 at the power and the root will cancel out and the 2 will be left )

so 36-2= 34 is the answer

Answer 2

Answer:

Surds are boring...

The answer is this:-19.48 or this:-12 + 6$\sqrt{5}$ - 2$\sqrt{2}$ - $\sqrt{10}$

Step-by-step explanation:

(6-√2)(2+√5)

= 12 + 6$\sqrt{5}$ - 2$\sqrt{2}$ - $\sqrt{10}$

None share common roots or roots that can be broken down so this is your answer

12+ 6*2.24 - 2*1.4 - 3.16

= 19.48  mark me as brainiest bcos I went the extra mile to solve this. Thanks!
