factor (xy-1)(x-1)(y+1)-xy

factor

(x y - 1) (x - 1) (y + 1) - x y

x^{2} y^{2} + x^{2} y - x y^{2} - 3 x y - x + y + 1

Solution steps

(x y - 1) (x - 1) (y + 1) - x y

Expand

(x y - 1) (x - 1) (y + 1) : x^{2} y^{2} + x^{2} y - x y^{2} - 2 x y - x + y + 1

= x^{2} y^{2} + x^{2} y - x y^{2} - 2 x y - x + y + 1 - x y

Simplify

x^{2} y^{2} + x^{2} y - x y^{2} - 2 x y - x + y + 1 - x y : x^{2} y^{2} + x^{2} y - x y^{2} - 3 x y - x + y + 1

= x^{2} y^{2} + x^{2} y - x y^{2} - 3 x y - x + y + 1

\frac{x ^{3} y ^{- 5}}{x ^{7} y ^{- 7}}

0.15 t^{2} = 150 - 4 t

7 (x + 2) = 42

3^{5}

lo g_{2} (32) = x
