Answer:
10+√2
Step-by-step explanation:
Here √2 is common so we can take it as x and use formula
(x+a) (x-b) = = x²+x(a-b)-ab
Here a= 3 , b= 4 and x= √2
(3 + √2)(4 − √2)
(√2)^2+ √2(3-4) - (3*4)
= 2 + (-√2) - 12
= -10 - √2
multiplying the whole equation with -1, we get ,
=10+√2
if we don't have the value of √2 then this is the simplest form.
