You are almost right, the first case means x equals a OR b is true Lazy evaluation means that the expression will be evaluated only until the result is obvious In an OR expression, for example (x y), the result will be known when x==true – then the whole expression must be true too In the case of AND, like (x && y), the result will be evident when x==falseFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with stepbystep explanations, just like a math tutorIt is basically an algebraic expression and also a binomial The square of this expression is written as ( a − b) 2 in mathematical form and it is expanded as a 2 − 2 a b b 2 mathematically In mathematics, this algebraic identity is used as a formula and it is called in the following three ways The square of difference of the terms formula Dge2q4znofr3nm ƒƒbƒNƒE[ƒ‹ ƒOƒ‰ƒXƒE[ƒ‹ ˆá‚¢ ŽÕ‰¹
