`(3x+15)/(5x+25)`

Find the products: (3/x-5/y)(9/(x^2)+(25)/(y^2)+(15)/(x y))

Find the products: (3+(5)/(x))(9-(15)/(x)+(25)/(x^(2)))

If x=3 and y=-1, find the values of each of the using identity: ((5)/(x)+5x)((25)/(x^(2))-25+25x^(2))

Solve : (x+3)/(7)-(3x-5)/(5)=(2x-5)/(3)-25

(x+3)/(7)-(2x-5)/(3)=(3x-5)/(5)-25

Simplify using following identiy: (a +- b) (a^(2) ab + b^(2)) = a^(3) +- b^(3) (3x- (5)/(x)) (9x^(2) + 15+ (25)/(x^(2)))

(10x^(2)+15x+63)/(5x^(2)-25x+12)=(2x+3)/(x-5)

Solve the following equation: (10x^2+15x+63)/(5x^2-25x+12)=(2x+3)/(x-5)
