    Step-by-step explanation:

    Let 3-√2 be a rational number hence, 3-√2=a/b,where a and b are integers and b is not equal to 0…

    3-√2=a/b

    √2=a/b-3

    =√2=a-3b/b

    here a-3b/b are rational numbers as a and b are integers but √2 is irrational numbers.

    Therefore,the contradiction we suppose is wrong hence,3-√2 is irrational numbers.

    when we subtract an irrational number from another irrational number, the difference is also irrational.
