UNDERSTANDING:
A. MULTIPLE CHOICE: Read each item carefully then choose the letter of the
correct answer.
36) A student claims that (b + 4)2 = b2 + 16. Do you agree with this?
Why? Why not?
37)
a) Yes I agree, because using laws of exponents which is power of a
power, the exponents are simply being multiplied.
b) No I dont agree, because the product of (b + 4)2= b2 + 4b + 16 which
is a quadratic trinomial.
c) No I dont agree, because the product of (b + 4)2 = b2 + 8b + 16
which is a perfect square trinomial.
d) Yes I agree, because I dont see any wrong with the answer.
38) Which of the following obtains sum and difference of two cubes?
