Question

reduce to the lowest term​

Answer 1

(a^2 - b^2)/ab - (ab-b^2)/(ab-a^2)

a^2/ab - b^2/ab - b(a-b)/a(b-a)

Now common (-) sign in denominator of last term and -×- becomes +.

a/b - b/a + b(a-b)/a(a-b)

a/b - b/a + b/a

= a/b

hence ans is a/b

Answer 2

Answer:

your answer

Step-by-step explanation:

(a^2-b^2)/ab- (ab-b^2)/(ab-a^2)

a^2/ab - b^2/ab - b(a-b)/a(a-b)

Now common (-) sign in denominator of last term and -x- become +

a/b - b/a + b(a-b)/a(a-b)

a/b - b/a + b/a

a/b
