Answer 1

3) {6m-2m+2}/{m(m-1)={4m+2}/{m(m-1)

{b-3b-6}/b(b+2)=(-2b-6)/b(b+2)

{8a^2+15a^2}/12(a+1)=23a^2/{12(a+1)}

(8x-15x}/10(x-3)=-7x/10(x-3)

{5x+5y-3x+3y}/(x-y)(x+y)=(2x+8y)/(x^2-y^2)

(4p-4q+2p+2q)/(p+q)(p-q)=(6p-2q)/p^2-q^2)

 

5b/a(x+y) -2a/b(x+y)={5b^2-2a^2)/{ab(x+y}

3x/4(x+y)-6x/8(x+y)={6x-6x}/8(x+y)=0

 

Answer 2

{6m-2m+2}/{m(m-1)={4m+2}/{m(m-1)

{b-3b-6}/b(b+2)=(-2b-6)/b(b+2)

{8a^2+15a^2}/12(a+1)=23a^2/{12(a+1)}

(8x-15x}/10(x-3)=-7x/10(x-3)

{5x+5y-3x+3y}/(x-y)(x+y)=(2x+8y)/(x^2-y^2)

(4p-4q+2p+2q)/(p+q)(p-q)=(6p-2q)/p^2-q^2)

 

5b/a(x+y) -2a/b(x+y)={5b^2-2a^2)/{ab(x+y}

3x/4(x+y)-6x/8(x+y)={6x-6x}/8(x+y)=0
