Simplifying 4x4 = 12x2 Solving 4x4 = 12x2 Solving for variable 'x'. Reorder the terms: -12x2 + 4x4 = 12x2 + -12x2 Combine like terms: 12x2 + -12x2 = 0 -12x2 + 4x4 = 0 Factor out the Greatest Common Factor (GCF), '4x2'. 4x2(-3 + x2) = 0

we have


4x^5-12x^4+6x=5x^3-2x

Separate the equation above in two equations

equation
1


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

equation
2


y=5x^3-2x

we know that


In a system of equations the roots of the equation
1 must satisfy equation
2 and the roots of the equation
2 must satisfy equation
1

therefore

the answer is

The system of equations is


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


y=5x^3-2x
