Can someone check my answer for this one?$$((x^2+9x+20)/(x^2-11x+28)) \div ((x^2+8x+15)/(x^2-3x-4))$$

Yup, thats right =)

Thank you! This one seems easy but i got stuck...If you can, will you help me w/ this one? And i'm really sorry about these equations, i know they don't look good.$$((x^2+12x+36)/(x^2-8x+12)) \div((x^2-36)/(1))$$

My answer is probably wrong: (x+6)/(x-6)^2(x-2)
