The values of the rational numbers a and b satisfying the square of |ab-2(1-a)=0.(1) a and b are ()();

The values of the rational numbers a and b satisfying the square of |ab-2(1-a)=0.(1) a and b are ()();

Rational numbers a and b meet
|Ab-2(1-a)^2=0
If both terms are non-negative and sum is 0, then both terms are 0
Ab-2=0 and 1-a=0
Then a =1, b =2

The rational numbers a and b meet
|Ab-2(1-a)^2=0
If both terms are non-negative and sum is 0, then both terms are 0
Ab-2=0 and 1-a=0
Then a =1, b =2

The rational numbers a, b satisfy |a-1||b-2|=0, find the values of ab, a/b,|a||b|.

Rational number a, b satisfies |a-1||b-2|=0
Then a=1, b=2
Then ab=2, a/b=1/2,|a||b|=3
