Question

solve (3+√2)(2-√3) answer fast this question​

Answer 1

(a-b)(a+b)=a²-b²

The above expression completely fits in this equation:

let’s substitute 2 with a: 2=a and √3 with b: √3=b

This will equate to 2²-(√3)²

The square exponent of (√3)² will cancel the under root and make it 3

Squaring 2 will give you 4

Now 4–3=1

Answer 2

Step-by-step explanation:

Let p = √(2+√3) + √(2-√3) , squaring both side

p ^2 = ( 2+ √3) + (2- √3) +2 √{(2+√3)(2- √3)}

or, p^2 = 4+2*√(4 -3)

Or, p^2 = 4 + 2*1= 6

or , p = ±√6

So, √(2+√3) + √(2-√3) = ±√6 = +√6 ( ignoring negative value )
