Answer 1

1. (3)/(x+3) + (2)/(x+1)
= (3(x+1)+2(x+3)) / (x+3)(x+1)
= (3x+3+2x+3)/(x^2+3x+x+3)
= (5x+9)/(x^2+4x+3)

2. (m+4)/(m^2-7m+12) x (m-3)/(m^2-16)
= (m+4)/((m-3)(m-4)) x (m-3)/((m-4)(m+4))
= 1/(m-4)(m-4)
= 1/m^2-8m+16

3. (2p+4)/(2p^2+2p-12) x (p-3)/(p^2-4)
= (2(p+2))/(2p-4)(p+3) x (p-3)/(p-3)(p+2)
= (2(p-3))/((2p-4)(p+3)(p-2))
= (2(p-3))/(2p^3-2p^2-16p+24)
= (2(p-3))/((2(p^3-p^2-8p+12))
= (p-3)/(p^3-p^2-8p+12)
