1)What method(s) would you choose to solve the equation:
x2 + 2x  6 = 0
A. Square roots; there is no xterm.
B. Quadratic formula, graphing; the equation cannot be factored easily since the numbers are large.
C. Factoring; the equation is easily factored.
D. Quadratic formula, completing the square or graphing; the coefficient of x2term is 1, but the equation cannot be factored. <<<
2)What are the solutions of the equation?
c^2  10c = 0
A. 1, – squareroot10 <<<
B. 0, –10
C. 0, sqrt10
D. 0, 10
3)Use the discriminant to determine the number of realnumber solutions for the equation:
8x2 + 8x + 2 = 0
A. one solution <<<
B. two solutions
C. no solutions
D. infinitely many solutions
4)What are the solutions of the equation: z2  12z + 36 = 0?
A. 6, 6 <<
B. 6, 6
C. 6, 6
D. 6, 6
am i right? if not, please help me out. :D
thank u!

1. I would choose B.
2. c^2  10c = c(c10) = 0
Now what do you think?
4. z^2  12z + 36 = (z6)(z6) = 0
Now what do you think?
3. Since it seems like you are just guessing, I did not bother to answer.posted by PsyDAG
