Question

How to solve simultaneously:

x^4-6x^2+60x+36=68x+39

Answer 1

combine the like terms ans solve...

Answer 2

yeah and?

Answer 3

i did combine both and equaled the equation to zero

Answer 4

that will be the answer....

Answer 5

i need to factorise the equation

Answer 6

how to factorise a quartic

Answer 7

yup i know... then use a quadratic formula and solve...

Answer 8

the x-coordinate of the point it intersect is -1 so the when factorising it: (x+1)... and i don't know the rest

Answer 9

pk tell me, how you simplified this for factors....?

Answer 10

do you know how to factorise the rest?

Answer 11

\[x^4-6x^2-8x-3=0,put x=-1,1-6+8-3=0,0=0,so x+1 is a factor\]
divide synthetically by -1 or divide by x+1 long division.

Answer 12

What does "simultaneously" mean with only one equation?
