1. ### Solving Polynomial Equations

yes it is :biggrin: you have to move it to the left side to get -20 then f(5)=0
2. ### Determine Roots

K though I wasn't taught that formula so....yea... must be another way
3. ### Determine Roots

yes thanks guys, lol u think i'm taking advantage?
4. ### Determine Roots

here is another pickle.... Find Real ROots y=x^4-4x^2-9x+36 AND NO I"M NOT ASKING YOU TO DO MY HOMEWORK, I TRIED THESE DAMN THINGS grrrrr
5. ### Determine Roots

THanks I got the answer my friend mr data. I'm so smart :) YOu caught me :D
6. ### Determine Roots

help me though :D
7. ### Determine Roots

where did u pick up that equation from...
8. ### Determine Roots

What are the ROots: x^4+4x^3+14x^2=-4x-13 ok the 13 really causes a problem because you can't factor that. So I move the right side to the left and then you can't find a number that fits so that it equals zero so I tried factoring it somehow but can't do it can someone help?
9. ### Solving Polynomial Equations

A box has dimensions that are linear factors of (x^3-7x^2+14x-8) cubic centimetres. What dimensions give a volume of 12 cm cubed? I started it off by moving 12 to the left side giving the equation: x^3-7x^2+14x-20=0 then from then I don't know....If I substitute 5, the equation is...
10. ### Easy Question

thank you my friend
11. ### Easy Question

oh so ur saying that when adding them you have to have the same x value
12. ### Easy Question

but whats the equation of f(x)=? It looks like you set x to zero why does left side -4 stay the same .....?
13. ### Easy Question

wouldn't it be (-8,6)
14. ### Easy Question

honestly i'm confused... f(x)=-4x+4? etc....? It's not (-4,4)+(-4,2)
15. ### Easy Question

Let f = {(-4.4),(-2,4),(1,3),(3,5),(4,6)} and g = {(-4,2),(-2,1),(0,2),(1,2),(2,2),(4,4)} Determine a)f + g
