Find the LCD then make it into similar:
-3y/x-1 , 4y^2/x^2-1
i just rewrite it but i need your answer

You will need brackets around the denominator to obtain the proper order of operations
your second fraction factors to
4y^2/((x-1)(x+1))
so the LCD is (x-1)(x+1) or the original x^2 - 1
so you have
-3y(x+1)/(x^2 - 1) and 4y^2/(x^2 - 1)
your second fraction factors to
4y^2/((x-1)(x+1))
so the LCD is (x-1)(x+1) or the original x^2 - 1
so you have
-3y(x+1)/(x^2 - 1) and 4y^2/(x^2 - 1)
