(yo u a re) (g a y - 1)

e a^{2} y^{2} o u r g - e a yo u r

求解步骤

(yo u a re) (g a y - 1)

= (e a yo u r) (a y g - 1)

使用分配律:

a (b - c) = ab - a c

a = (yo u a re), b = g a y, c = 1

= (yo u a re) g a y - (yo u a re) \cdot 1

= a y g (e a yo u r) - 1 \cdot (e a yo u r)

化简

a y g (e a yo u r) - 1 \cdot (e a yo u r) : e a^{2} y^{2} o u r g - e a yo u r

= e a^{2} y^{2} o u r g - e a yo u r
