Question

i just need to know a method to do this. like quadratic formula but this isnt that
x^3+6x^2+50x=20x^2+10x

Answer 1

1. Put all things to the left hand side
2. Factor out x
3. See what you're left with

Answer 2

nicely explained kc

Answer 3

i got x^3-14x-40x=0

Answer 4

@perl will you stop doing everything

Answer 5

x(x^2 - 14x + 40) = 0
(x - 4)(x - 10) = 0

x - 4 = 0
x = -4

x - 10 = 0
x = 10

Answer 6

you too @kelliegirl33

Answer 7

x^3+6x^2+50x = 20x^2+10x
x^3+6x^2+50x - 20x^2 -10x=0
x^3 -14x^2 + 40x = 0
x( x^2 -14x + 40 ) = 0
x = 0 or x^2 -14x + 40 = 0
x = 0 or (x-10)(x-4)=0
x=0 or (x-10) = 0 or (x-4) = 0
x= 0 or x = 10 or x = 4

Answer 8

my bad...sorry bout that

Answer 9

so i got x=0, x=4, or x=10 as my final answer

Answer 10

@kelliegirl33 it's fine :)

Answer 11

x = 4 and x = 10...I messed up before and put -4, but it is 4.
