My instructer is posting a test Thursday. The following are some examples of what is going to be on the test. Any help will be greatly appreciated!
1) Factor this trinomial: x^2 - 11x - 60
2) Factor 2 a^3 - 52 a^2 b + 96 a b^2
3) Find positive values of k which make x^2 + x - k factorable.
4) Factor 14 x^2 - 20 x + 6 completely.
5) Factor -35 s^2 - 10s + 8 completely.
6) Factor the binomial 25 x^2 - 81 y^2
7) Determine whether x^2 - 24 x + 48 is a perfect square. If it is, factor it.
8) Factor the trinomial 16 x^2 + 40 x y + 25 y^2
9) Factor the expression a^2 (b - c) - 16 b^2 (b - c)
10) Factor x^3 - 4 x^2 + 2 x - 8 by grouping the first and last two terms.
11) Factor completely: 3 a^3 + 3 a b^2 + 2 a^2 b + 2 b^3
12) Use the A-C test to determine if x^2 + 2x - 15 can be factored.
13) Use the A-C test to determine if x^2 - 3x + 7 can be factored.
14) Rewrite the middle terms of 12 w^2 + 19 w + 4 as the sum of two terms, and then factor.
15) Factor 4 z^3 - 18 z^2 - 10 z
I am so failing and not understanding so maybe someone can give me a little help, thanks!
