Answer:
4(x+2) / 5(x-1)
Step-by-step explanation:
We have given two expressions.
2x / x-1 expression I
5x / 2x+4 expression II
we have to find the quotient of expression I and expression II.
(2x / x-1 ) ÷ (5x / 2x+4)
Applying following rule:
a ÷ b = a× 1/b
(2x/x-1)×( 2x+4 / 5x)
(2x)(2x+4) / (x-1)(5x)
(2)(2)(x+2) / (x-1)(5)
4(x+2) / 5(x-1) which is the answer of given question.
