Question

find the value of (3+2√2) (3-2√2)

Answer 1

Hii friend,

(3+2✓2)(3-2✓2)

we know that,

(a+b) (a-b) = a²-b²

A = 3 and B = 2✓2

Therefore,

=> (3)² - (2✓2)²

=> 9 - 8

=> 1

HOPE IT WILL HELP YOU.. :-)

Answer 2

Heya ✋

Let see your answer !!!!

(3 + 2√2) (3 - 2√2)

We apply these formula here

(a + b) (a - b) = a^2 - b^2

= (3 + 2√2) (3 - 2√2)

= (3)^2 - (2√2)^2

= 9 - 8

= 1



Thanks :))))
