## skate2400 3 years ago What polynomial has roots of -6, -4, and 1 ? x3 - 9x2 - 22x + 24 x3 - x2 - 26x - 24 x3 + x2 - 26x + 24 x3 + 9x2 + 14x - 24

1. cwrw238

(x+6)(x+4)(x-1) = 0 has these roots which will expand to one of your options

2. cwrw238

= (x-1)(x^2 +10+24)

3. cwrw238

that narrows it down to 2nd or 4th (-24)

4. cwrw238

that should be 10x in second parentheses

5. cwrw238

expansion will give -10x +24x - so which ne do you think it is?

6. skate2400

i think the 3rd one?

7. cwrw238

nope -10x + 24x = +14x

8. cwrw238

check out the one with +14x in it

9. cwrw238

it cant be the 3rd one as it contains +24 - - see above - it must contain -24

10. skate2400

shoot ok let me see

11. skate2400

the last one right? i didnt even see the 14x haha

12. cwrw238

right - hope you dont mind me 'playing' with you - they like us to guide you through on this site - not just give you the answer

13. skate2400

no i understand i rather understand how to solve it then just get an answer :]
