\[12x^2+10x-16 \] \[9999x^2+9000x-4500 \] no calculators.... no online materials... all by using the quadratic formula and the discriminant formula. Have fun :)

try x^4 - 2x^3 - 20x^2 - 8x - 96
welshfella
  • welshfella
Hint :- factor 96

(x+4) (x-6) (x+2) (x-2)
welshfella
  • welshfella
no cant be right because the numbers multiply out to +96
UsukiDoll
  • UsukiDoll
did you do that on your own??? xS looks wolframish
welshfella
  • welshfella
this is not easy

Yup..I used Synthetic Division.....

(x + 4) is a factor
anonymous
  • anonymous
What is the right answer then?
welshfella
  • welshfella
(x^2 + 4)(x+4)(x-6)
anonymous
  • anonymous
OH fudge....I factored (x^2 + 4) thinking it was (x^2-4) /facepalm Thanks anyway.

he was close though

  • welshfella
yes good effort
UsukiDoll
  • UsukiDoll
wanna try mine lol?
welshfella
  • welshfella
I dont think yours will factor

I'm having a hard time in your problem xD Can you show me a step by step solution so that I could analyze it thoroughly?
UsukiDoll
  • UsukiDoll
I'm not going through that D:
welshfella
  • welshfella
you'll need to use quadratic formula i think
UsukiDoll
  • UsukiDoll
oh yeah... I gave the two formulas to use XDDDDDDDDDDDD
UsukiDoll
  • UsukiDoll
discriminant formula and quadratic formula. first formula is awesome.. because you already have the b^2-4ac part
UsukiDoll
  • UsukiDoll
then when you use quadratic formula, you find the roots ... and write in factor form, so in the end you did factor... just in extra steps :P

@UsukiDoll, regarding your first equation, this is my answer. \[(x-8) (x+\frac{ 17 }{ x-8})\]

oh my not even close...

What?! Can you please give me the answer? Just the final no need for solution. I will try to make a solution for that final answer.
