I'm not sure how to solve these problems.
(3xsquare - 2x)divided by 15x - 10
(2y/x-y) - 5x/4y
(27/x) = (8 - 5/x)
(7m^7n^4/8m) divided by (9m^2n^9/5n^2)
1) 3x^2 - 2x/ 15x - 10
factorize both the numerator and denominator
= x/5 (the 3x-2 cancel each other
2) 2y(4y)-5x(x-y) / 4y(x-y)
The x-y cancel each other
8y^2 - 5x / 4y
4y goes in 8y^2 2 times
so the answer is
2y - 5x
3) NOT SURE ABT THAT
but i know that the 9m^2... part is gonna be multiplied to the 7m^7 part
CHECK UR WORKING OUT
