Top-left of page 36 example has a typo: should be 2x^2 instead of x^2.
Some writing on top of page 99.
Question #9 in examples II, the square root was not printed correctly.
Answer Key V Ex. III question #14 and #16 answers, the square roots were not printed well.
Answer Key Ex V Question #9, the answer should be (30a^5)(b^7)(c^3), not (30a^6)(b^7)(c^3)
Answer Key Ex V Question #11 should be (-42x^(5/2))(y^2), not (-42x^(5/3))(y^2)
*
Answer Key EX VIII
#5 Answer should be: 4(m^6)+12(m^5)(n)-24(m^4)(n^2)+64(m^3)(n^3)-72(m^2)(n^4)+32(m)(n^5)-20(n^6)
NOT 4(m^6)+12(m^5)(n)-24(m^4)(n^2)+6(m^3)(n^3)-72(m^2)(n^4)+32(m)(n^5)-20(n^6)
#7 Answer should be: x^5 + 3(x^4)(y)-28(x^3)(y^2)+3(x^2)(y^3)+12(x)(y^4)-63(y^5)
NOT x^5 + 3(x^4)(y)+28(x^3)(y^2)+3(x^2)(y^3)+12(x)(y^4)-63(y^5)
#16 Answer should be: x^7-10(x^6)+3(x^4)+30(x^3)+6x-60
NOT: x^7-10(x^6)+3(x^4)+30(x^3)+6x-30
I hope this helps for the 2nd edition of the book!
