try factoring :)

so, I'd remove the x^2 from the first two terms, making it x^2 (x  12 + 28x  9)?

and then combine like terms, making it x^2 (29x  21)

... you can't just remove x^2 from the front. what about the back? you get x^2(x  12) + 28x  9

start by hit and tril, put x=1, 1, 2, 2 till u get f(x)=0

try ur self till u get f(x)=0 after that v proceed next

let "a" is that value ie f(a)=0 means "a" is a root and xa is a factor, now divide the original equation by xa to get another factor(that will b quadratic, factorize that and equate the three factors one by one to get the roots,

ok sigh i don't know what he was doing

RONNCC Group TitleBest ResponseYou've already chosen the best response.0
but via factoring you get (x9)(x^23x+1)

RONNCC Group TitleBest ResponseYou've already chosen the best response.0
therefore x = 9 and you use the quadratic formula to find the roots for x^2  3x + 1

I'm having trouble using the quadratic formula with (x^2  3x + 1)

\[a=1,b=3,c=1\] \[x=\frac{b\pm\sqrt{b^24ac}}{2a}\]

DeadShot Group TitleBest ResponseYou've already chosen the best response.0
so, a=1, b=3, and c=1?
