Question 419144
1: (x^2/x^2+2x+1) / (3x/x^2-1)


{{{(x^2/(x+1)^2)/(3x/(x^2-1))}}}


{{{(x^2/(x+1)(x+1))*((x+1)(x-1)/3x)}}}


{{{x(x-1)/3(x+1)}}}

.......

2: (2x+4/3x-3) * (12x-12/x+5)

{{{(2(x+2)/3(x-1))*(12(x-1)/(x+5))}}}

{{{8(x+2)/(x+5)}}}

.....



3: (7/2xy^2) + (3/8x^2y)
LCD = 8x^2y^2

{{{(28x+3y)/8x^2y^2}}}
