Помогите решить, пожалуйста , срочно.
b a+b
_______ - ____________
(a-b)² b²-ab
(b*b+(a+b)*(a-b))/(b(a-b)²)=
(b*b+a*a-b*b)/(b(a-b)*(a+b))=
a*a/(b(a-b)²)
_______ - ____________ =
b a+b b a+b
= _______ - ____________ = _______ + ____________ =
(a-b)² b(b - a) (a-b)² b(a - b )
b² + ( a + b)(a - b ) b² + a² - b² a²
= __________________________ = _______________________ = ________
b(a - b)² b(a - b)² b(a - b)²

(b*b+(a+b)*(a-b))/(b(a-b)²)=
(b*b+a*a-b*b)/(b(a-b)*(a+b))=
a*a/(b(a-b)²)
b a+b
_______ - ____________ =
