3x^3-23x^2+7x+5 3x^3-24x^2+x^2+15x-8x+5 3x^3-24x^2+15x+x^2-8x+5 3x(x^2-8x+5)+1(x^2-8x+5) (x^2-8x+5)(3x+1)

Tedious, but it works
anonymous
  • anonymous
wow.. ;) thanks
Hero
  • Hero
now you can do this: (x^2-8x+5)(3x+1) = 0 x^2-8x + 5 = 0 3x+1 = 0 and solve for x

Aahh i'm lost even before i got to the third step.. ;l how did 3x^3-23x^2+7x+5 become 3x^3-24x^2+x^2+15x-8x+5?
Hero
