Which system of equations can be used to find the roots of the equation 4x^5-12x^4+6x=5x^3-2x?

A). Y=-4x^5+12x^4-6x and y=5x^3-2x
B). Y=4x^5-12x^4+5x^3+4x and y=0
C). Y=4x^5-12x^4+6x and y= -5x^3+2x
D). Y=4x^5-12x^4+6x and y=5x^3-2x

Respuesta :

D is the answer......................

Answer:

D). Y'= [tex]4x^{5}-12x^{4}+6x[/tex] and y'= [tex]5x^{3}-2x[/tex]

Step-by-step explanation:

We are given the equation [tex]4x^{5}-12x^{4}+6x=5x^{3}-2x[/tex].

On simplifying this equation, we get [tex]4x^{5}-12x^{4}-5x^{3}+8x=0[/tex]

i.e. Let, Y'= [tex]4x^{5}-12x^{4}+6x[/tex] and y'= [tex]5x^{3}-2x[/tex]

Now, according to the options,

A) Y =  [tex]-4x^{5}+12x^{4}-6x[/tex] = -Y' , that means the graph will be inverse of the required graph.

B) As the coefficient of 'x' in our given equation and the equation of option B are different, both will have different graphs.

C) As y =  [tex]-5x^{3}+2x[/tex] = -y', this means that the graph will be inverse of the required graph.

Hence, all above options are discarded and so option D is correct.
