For the polynomial below, -2 is a zero.
f(x) = x^3 - 2x^2 - 6x + 4
Express f(x) as a product of linear factors.
Thank you for the opportunity to help you with your question!
-2 is a zero
The answers I am supposed to get for these when they involve big fractions have been using radicals
yes you can also find roots using that method
lets solve for this
here a=1 b=-4 c=2
x1=2 + sqrt(8)/2
did you get it???
Im confused on how id write that
directly ask me algebra questions i will give explanations to you.
f(x) = (x+2) (x-(2+√8/2)) (x-(2-√8/2))
