Question

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

Answer 1

hello :   The answer is D,

the last system

the system is ;  

y =4x^5-12x^4+6x

y = 5x^3-2x

Answer 2

We are given equation : $4x^5-12x^4+6x=5x^3-2x$.

We need to find the system of equations can be used to find the roots of the given equation.

We can see that left side of the equation is $4x^5-12x^4+6x$.

And Right side of the eqaution is $5x^3-2x$.

So, we could set each of the left and right side expression equal to y.

We get

$y=4x^5-12x^4+6x$ and

$y=5x^3-2x$ are the system of equations can be used to find the roots of the equation $4x^5-12x^4+6x=5x^3-2x$.
