|
Anu pose la question : The expression (x+y+z)^2006 + (x-y-z)^2006 is simplified by expanding it and combining like terms.
How many terms are in the simplified expression?
I've spent hours on this. pls help!!!
Also, is answering these questions a paid job for you or is it volunteer work?
I'd like to join an ask and answer site for math, (when I grow up)

Cubic polynomials |
2007-08-14 |
|
Jalon pose la question : The cubic function f(x) = (x+2)^3 touches the x axis only once at x = -2 (negative two). it could also be written as f(x) = (x+2)(x+2)(x+2)
Investigate the cubic functions below as well as the one above and comment clearlt and fully on where they touch/intersect the x axis, and how these points relate to the given function.
a) f(x) = (x – 3)(x +4)(x – 2)
b) f(x) = x(x + 1)^2 (^2 = that means it squared)
Your comments should reference graphs illustrating your conclusions and display another 2 trinomial graphs that demonstrate your conclusions. particular attention should be given to the number of times your function crosses or touches the X axis.
i dont know how this works but could you send the answer to..... spongy_91@hotmail.com Stephen La Rocque lui répond. |

A student pose la question :
I'm having trouble factoring expressions that aren't monic. I can do things like
x2-9x+8, but problems like 12x2+5x-3 have me stumped.
I also have a question about factoring out common factors. In a problem like
x2-18x+81, wouldn't you divide by 9? But what happens to the x2, is it x2/9? Penny Nom lui répond. |

(1+z+z^2)^2 |
1998-09-10 |

A.R. pose la question : These questions deal with factoring. (1+z+z^2)^2 and (p^2-pq+q^2)^2 I partially understand the second line which would be 1+z^2+z^4+2z+2z^2+2z^3 but I don't understand where the 2 comes from in the second half of that line. p.s.(^2 means squared or cubed etc.) Please help me out A.S.A.P.! I have a quiz on this tomorrow! Thank-you, A.R. Harley Weston lui répond. |
